First, I will take the word of a reputable company (in this case 3) specializing in the area that I am researching, that's just called common sense. Who are you to knock on any company that has an R&D department of people that are a lot more capable than you and out number you by double digits. Seriously, as smart as you think you are, I and anyone else with common sense will always go with the experts in the field. Stylis from precision muffler does this for a living and will help you if you have any questions unconditionally, not just for you to buy an exhaust. Most of the people are on here to help, there is nothing wrong with offering a product, and the companies mentioned are very reputable and trustworthy. Do YOUR research before you slam anyone else on this forum. And this is my favorite part: "and FYI i'm an expert in both domestic and import performance because i get off my a$$ and do the real time research my self" what a joke.

Second, I work two jobs and go to a university full time, I am hardly home. I could not find a tape measurer to measure my stock exhaust, but even if I did, there is no way to measure the inside of the pipe because it is slightly larger at the connecting points. Therefore the actual measurement can only be attained by slicing the pipe, then measuring it.

Third, the reason your beloved Japanese companies make 60mm axle back is because 55mm would be too small. 60mm = 2.362" 55mm = 2.165"

Last, the link to the thread shows conversions, take another look at it and pay closer attention to "pipe size" and "surface area".

 

I know man thats why I'm LMFAO right now our piping is 2.25 and 2.5 in certain spots give or take a fraction here or there, honestly who cares about those .02 inches that Toyo shrunk it. We have have a thread, two people that appear to have measured it (you and mid life tc-risis), and he has the word of three manufactures. Sorry but my entire exhaust now consist of a 2.5 invidia spipe, 2.5 magnaflow catback, all 2.5 with the exception of the area with the bubble cat-converter. Oh wait, maybe mines 2.48 and 2.52 at some points where they overlap

 

LOL not to burst your bubble but Invidia s-pipe is 60mm, and which Magnaflow are you talking about, because the only Magnaflow cat-back they make for our car is 2.25". You also have to take into consideration that all figures should be Inner Diameter, not outer.

 

Sorry to burst your bubble...http://www.invidia-usa.com/Products.aspx?ProductID=138
OD 2.5 ID 2.4 from the guy with the caliper, guess since he doesn't work for magnaflow he doesn't know **** and can't read a gauge. As I post in the post right above yours, I don't give a crap about a few measly tenths or hundredths of an inch, until your F/I it's not going to do you a d@mn thing, except the s-pipe...that is the most beneficial mod for the exhaust...excluding a header of course. You are correct on the magnaflow, I looked at the OD on my install sheet, but again see the above post.

And on that note, we SOOOOO totally thread jacked this!

 

amdforever, the Invidia's I/D is exactly 60mm. The link to their official website does not specify dimensions. Here, this will help you, https://www.scionlife.com/forums/viewtopic.php?t=137915 go to page 2.

As far as preferred dimensions, 60mm is perfect for all motor application in our cars, 2.5" may lose bottom end torque. I have a skunk2 s-pipe back (60mm) and love it. The .11" in diameter do make a difference when you take exhaust flow into account.

Also, Magnaflow sarcasm is not nessary. The point of this forum is to assist one another in accurate and helpful manner. The companies, that come on here with false, unsubstantiated claims do not last. Look at ScionSpeed, they got sued and no longer here. Reputable companies or even people, have no reason to fool or mislead anyone. If they have a proven product they have no motivation to sell you an item under false pretenses.

 

Dude, your cracking me up, you DOOOO realize this thread was about stock sized piping, not the aftermarket ones? Your the one the brought aftermarkets into this. "Also, Magnaflow sarcasm is not nessary." Um where the f' did I say anything sarcastic about Magnaflow? Oh and as you stated..."60mm=2.362 inches" Well buddy, last time I went to school that rounds up to 2.4, which is what that guy said in the link that I posted for you, if you even read it. And on that note, just goes to prove that I still don't give a d@mn about .1" of exhaust piping. You need a little back pressure to help maintain your torque, that I know, and I don't really care, my car lives in the high RPMs and my header helped put back a little lowend...not that I even knew it was missing. Assisting one another is fine but when you start cutting others down when they take the time to actually measure stuff, then wheres the assisting part of that? Wheres the helpful manner? That's right, its not there b/c everyone that does help gets tired of the people like you that cut them down, and throw **** in their face for trying to help you in the first place. False companies appear everyday, they die everyday, and they will just pop up the next day, if none of your "companies" wanted to miss lead anyone then the would specifically state what size the pipe is that they are selling in "mm" since this is after all a foreign car and they don't use "inches" over there. And as much as I hate to break it to you. That ".11" " that does make a difference...I'm pretty sure its not going to make nearly as much of a difference than giving your car a nice smoothed out s-pipe. Oh and its funny that you back up the fact of "60mm" for the Invidia with what another company says...that isn't the original manufacture of it.

 

amd, it's a bit odd that you believe some random person that says he measured an item and it came out to X specification, yet when someone else uses actual pictures and formulas to describe an item, you question their credibility because they sell the item and not manufacture it? Thats very rational. I did mock him a little, yes, but that was to illustrate the irony in his self proclaimed expertise. Seriously, have you read what he wrote? He does get an A for effort though.

I also corrected you on the dimensions of your aftermarket exhaust, wouldn't you rather know the exact specifications of your setup? I don't understand why people get mad when they are corrected.

The link you gave me has nothing but product pictures. Thats the official Invidia site, I've been to it, no specifications.

Oh, and by the way; tC is made in Japan but not sold in Japan. Therefor all the specifications are intended for the market they are catering to, thats why it's not in mm.

Last, your sarcasm was: "OD 2.5 ID 2.4 from the guy with the caliper, guess since he doesn't work for magnaflow he doesn't know **** and can't read a gauge."

 

Um, why would I not believe him? He has a caliper, your guy has a picture and this disclaimer "The ID is trickier, by my inaccurate tape measure I'm going to call the ID 2.375." Hmmm yup no reason to question his credibility at all. Um ok so my "exact" dimensions are 2.4 for my s-pipe and 2.25 for the rest...sry, just don't see myself saying that to people when they ask me what I'm running on my car modwise, and frankly I don't think they care either. I'm not mad about being corrected. I get irritated when people try to help, others shut them down when they have more experience than the other person, then they proceed to argue on a point that isn't even valid in regards to the thread. This is so much fun isn't! It's my bad you got the wrong link, it didn't copy the new one for some reason but here is the guy with the caliper
https://www.scionlife.com/forums/arc..._0__index.html
Like I said, that's my bad for the bad copy/paste. Probably explains why you think I was being sarcastic towards Magnaflow...in fact it was towards you. Oh and just FYI, I bought my s-pipe from that guy... I'm just stating...dude with caliper vs dude with admitted messed up tape measure, who would you believe? The reason I'm not concerned about my setup is b/c it runs just fine the way it is, and until I go F/I with the plans that I have, then there is no need. Once finished then I will upgrade to 3" piping all the way back, whether thats ID or OD doesn't matter as I have 2-3 yrs to even care about it :D

 

Look amd, initialy I was arguing about stock dimensions, with a guy that measured it, but gave us inaccurate feedback. The reason this thread was created was to properly inform those that may not be aware of the dimensions and provide them with the most accurate information possible. This was not the case, so I cited my sources only to be shot down because they were "domestic, ignorant, and incompetent". Yet, the self proclaimed expert whom no one knows, is supposed to be more credible than the companies? What motivation do they have to lie, don't you think if inaccurate information was given out to the public, sooner or later they would catch on? If that's you rational then why even buy from companies like Magnaflow and Invidia,? Why don't you march to your local muffler shop and have them do it in front of your eyes, then measure it your self? My guess would be the quality and reputation the companies may have over that muffler shop.

As far as the Invidia pipe, there are no pictures of his caliper. I will always go with visible proof and make my own conclusion based on the information provided. That's why people post dyno sheets and time slips, so there is no argument. His estimate is pretty accurate, look at it and follow the math. Just because he corrected his previous statement doesn't mean his final outcome is flawed.

 

Well you have some good points...do I agree with them, mostly no. Like I said, I don't like seeing someone jump on someone else, especially since I've seen him around here on the forums giving out good info where available, and I've only seen you on here since this thread was created, thats says a lot to me....sure Mugetsu threw the first "slap" ,if you will, since he was ____ed at the work the he did and then you b!tch him out over it, but you came back with a punch and then it was just a 'verbal' fist fight after that. Childish...yeah, did I enjoy it, HELL YEAH! I mean, seriously, "The reason this thread was created was to properly inform those that may not be aware of the dimensions and provide them with the most accurate information possible." do you want me to comment on this? Well, I will, it may have started as someone asking a simple question, they did get a simple, answer, just read my first d@mn post, but by the time they sort through all the B/S that we just flooded this thread with, it is in no way helpful for them, other than to get a good laugh for the day....that's about it. So basically it all comes down the this...stock piping is 2.25 average, some parts are bigger, some are smaller, its mostly crap, the s-pipe is a mutated piece of ****, and buying an aftermarket one is the way to go. Get a nice 2.25-2.5 kit and your good to go, and yes 2.4 is close enough to be considered 2.5 in my book. Now can we shake hands and call truce, or do you want to keep at this until its locked?

 

See what happens when you don't visit Precisionmuffler.com

 

29inch Long and 7.5inchs Diameter. I am answering the original question of this topic.

 

^What the hell does that have to do with anything we were talking about?????

EDIT: DISREGARD :D You posted up as I was replying

 

Also people, you must understand that I am going by inches when the original diameters on the piping is by the metric system, so inches is not entirly correct. You must also understand that the S-pipe is known for having a pipe in a pipe set-up. So even though the S-pipe looks huge, you should cut one open and see your happy little metric sized pipe hiding. :D I got the PM and just had to come out and see all of this. I am still reading to find out the purpose of the finding out the sizes. We all know that aftermarket is better

 

I know i'm being overly harsh but damn...you are uselessly clueless...

Heres a little secret about your so called "experts" that you would lay down your life for.

Stylis at PM muffler...
it pains me to say anything bad about this guy cause he really has provided a great service to the scion community with his axleback exhaust. BUT in 05 this was the guy peddling a DUAL exhaust for the tc claiming in would increase performance in both NA and F/I...nuff said(sorry stylis had to sacrifice you to prove this fools...well foolishness...)

CC(creative compacts)
WHO?! these guys had their stuff manufactured in the back alley of one of MEGAN's plants...
their short shifter was an incomplete mod with no riser bushings that made shifting a tc feel like shifting a 82 manual chevy nova, their S-pipe had so many fitment problems that as far as i know they stopped making them...nuf said.

Megan
don't matter what you say about megan, their stuff is crap yet they pump it out by the hundreds and fools like YOU buy it like candy...

Magnaflow
they know trucks and american muscle, their "import performance" division is probably the janitors closet in their office building. YOU your self claimed that their catback was 2.5 mandrel bent NOW it turns out its 2.25 HMM...

And for my comment(which by the way thats your one trick pony cleverness, turning others comments and childishly ridiculing them) of expertise may not apply in the professional world
but against your dumbfounding idiocy I'M a frigging expert. mister 2 jobs and a university.

 

Actually I am still pushing the dual exhaust set-up and I already admitted that it does NOTHING FOR HP gain. I made that clear when I designed the darn thing. It was the TC OWNERS that wanted a dual set-up and I always give people what they want. So you might want to look up my dual exhaust thread again and check what I have said again. :D :D

No harm no foul. Just thought I would correct you about how I am not about fooling anyone and I am still about the Scion Community. Come out to PrecisionMuffler.com and join me for lunch sometime. I promise you'l have a great time, :D

 

You make me laugh, I can't even begin to fathom your reasoning and rational. "...expertise may not apply in the professional world
but against your dumbfounding idiocy I'M a frigging expert."

Let's take a look here:
Megan - Never said anything to the effect of quality. They do however provide value and a cheaper alternative. They have 2 exhaust products for our cars; Drift Spec (2.5" w/2.25" inlets) and OE-RS which retains the stock spec of 2.25", hence the OE (write this down since you can't actually glance at it and determine the size, shape, color, and whatever else you can do with your expert powers).

CC (Pro-Motion) - Great company, great service, look around the forum and see what the consensus is. Yes, they had a fitment issue with their s-pipe, and they handled it well to still have such support. Every company has a defect or design flaw once in a while. Real world application is a bit different than your original charts, you should know that mr.expert. Case in point: Toyota recalled almost 30,000 tCs because their side air bags would go off when the doors are slammed hard. They recalled god knows how many cars because of the hatch and the wind deflector. Maybe you should boycott Toyota, after all they are as guilty as CC. All companies big and small have issues once in a while, but to label them and define over an incident just shows your ignorance and biased opinion.

Precision Muffler - You have to be kidding me. This exhaust? http://precisionmuffler.com/id138.htm

Magnaflow - One of the most respected aftermarket exhaust companies in the world that operates in US and UK. Yet you, the self proclaimed "friggen expert" claim that their janitors oversee their import division. That's pretty funny, I give you that. As far as what I "claimed" about their exhaust; It's a 2.25" pipe that has a 2.5" opening at the point where you clamp it on the stock exhaust. If you would only spend half the effort looking at the facts presented to you, as opposed to refuting everything and everyone.

I want to ask you one more thing. How exactly did you arrive at 2.41" and 2.5" for the stock exhaust. What tool did you use, at what point, and what formula. Just humor me... (and please no more "I looked at it and I determined it by the contrast of the shapes and sizes...) or whatever else your gifted eyes allow you to do.

 

So is that a good thing or a bad thing.

 

I think its awesome and not too many people make dual exhausts. It's a little pricey for me considering its an axle-back you also need to do some body work. But to each is own, if I wanted to make a show car I would definitely consider it.

 

Considering he is backing all his info from manufactures, I'd say no...WOW this the most hilarious thread I've read in awhile It's like a d!ck measuring contest in here
