What is the point of a catback exhaust on our tc's? I could see changing the header and the rear section (muffler), It is mandrel bent already, sure the resonator is a little big but the exhaust is silent. You will still see a gain by a header and rear section. Its already stainless steel also. Just wanted some insight of what other people thinks?

bigger piping would be the key. more air flow. that 1/4 inch actually makes a differences. and the downpipe isnt quiet, the muffler is quiet.


in my case, i was plannin on gettin a 2 3/4 pipe and connect it to the stock muffler since the stock muffler baffles a lot of sound

Its a four cylinder n/a. 2.5 is plenty big enough. You need back pressure.

i would say get a good 60mm (2.36'') mandrel bent, resonated midpipe that works with the stock axle back.

it will give the gains of the traditional catback and still keep the sleek tc muffler look with the mature quiet sound...although it should sound more aggressive down low.

The car has 2.5" mandrel bent pipes stock. I just will probally get an axle back exhaust.

The car does not have 2.5 pipe on it. It only has pipe under 2.25inch.

He's right. It is 2.25 inches.

2.5 and 2.25 maks a bigg difference.

It only has pipe under 2.25inch.

You need to look at it again. The pipe that bolts up to the header is at least 3".

thats not the right size of the entire exhaust system, thats the down pipe. And it gets smaller after that.

the piping is NOT the same all the way through...the downpipe/front pipe is wider than the rest of the exhaust system

that difference in exhaust 2.25--2.5 is major, helps alot

u can get a full kit that is cat back and includes the front pipe---but they are
emissions illegal cuz it replaces the front cat

i have TRD exhaust now, but im waiting for my Borla catback system to arrive

all of the systems I have seen that are out or coming out are rear-axle back only. The Injen one has been selling out every time we get it in and I have been informed by GReddy that they will be releasing theirs soon. (GReddy also is working on a Turbo System for the tC). Anyway since the DC Header is NOT street legal you might as well have a muffler shop do custom piping to a nice APEXi Muffler or something if you really want to do the whole system (incl. Header) and go balls out w/ bigger piping (which I agree is not needed on a n/a car). Personally I am going to probably get the GReddy Evo2 when it comes out, it will be legal and look the best, IMO. I dont want to do the Header or custom piping, I did all that on my 3-Series and it was way to loud even for me!!! point is no companies I have heard of are bringing full cat-back systems to the shelves, because they know its pointless.

I know the entire exhaust isn't the same size. You said the bigest the exhaust gotten was 2.25, I was just stating that the exhaust gets bigger.

The car has 2.5" mandrel bent pipes stock. I just will probally get an axle back exhaust.

This is what you said, nothing specific about you stating anything about the exhaust GETS bigger.

You even had me look at it again! :shock:

CAN'T WE ALL JUST GET ALONG??

Well I know for a fact that Borla is bringing a cat back exhaust and performancemuffler.com (I think) has one already with a magnaflow muffler. There will definitly be catbacks for this car just give it time. AXLE BACKS ARE WEAK!

catback systems r already out for the car

go to www.creativecompacts.com and email james, he will give u pricing and other info

CAN'T WE ALL JUST GET ALONG??

oh I am not trying to fight anyone. I was just showing what was said. I could care less what size the stock pipe is on the tC. I just know that the stock system is lacking. :D

dude, im just messin---i kno no one has ne hard feelings here

and yes, the stock tC system is lacking---thats y we all upgrade!!!

lmao! Are you talking about o.d. or i.d. ? I am refering to o.d.

oh lord. :shock: I am done, :lol: Dude, why does it matter? the stock system is still lacking. :D

CAN'T WE ALL JUST GET ALONG??

Do you honestly think that'll happen?

There are way too many egos on this site for that to happen.

Everyone here is an expert of some sort, has thin skin, and second guesses what the other person has to say! That's why I try to keep my mouth shut. I got tired of it also!

oh lord. :shock: I am done, :lol: Dude, why does it matter? the stock system is still lacking. :D
Lacking because you sell aftermarket mufflers? ;)

Did you guys dyno your kits that you sell for tC?

I just wanted to know. It doesn't matter. I can see why its lacking. Any one know of a good quality catback with dyno to prove?

squirrel...yes i know this, iwas jokin when i said it

oh lord. :shock: I am done, :lol: Dude, why does it matter? the stock system is still lacking. :D

yes we dynoed, with cool numbers. But I am going to dyno it again on a newer , non outdated dyno. Need to get some real impressive numbers, plus we need to dyno with the CAI as well. :D

I haven';t seen any true dyno sheets yet, as far as any of the tC exhausts are concerned. I do know about the Injen exhaust dB test/video though, cuz I took part in it.

Well, when you get the dyno sheet - don't be shy, show us. And it better not be like with Weapon-R short ram...

DAM! :shock: Yes sir! :D

I should post up the dyno sheet from this other time, the torque really went up on the car after the catback was installed, :)

I'm not being a butt here - if you have a good product - show it off. If the numbers are good it will sell like hotcakes. Hell, I dropped $250 on a TRD muffler just because it sounds cool - and if something will make power besides the sound - I'm all for it ;)

no I understand that, but showing that you only get 4HP out of a catback is not really a big seller here.

"How much is that catback and I am only gettin how much out if it?"

See thats why I want to redyno the car on a newer dyno plus I need to redyno anyway with a cai.

Just keep us posted. I am trying to plan out a string and list of modifications to the tC. As more and more things come out I will start to replace and reorder things...

I love cars

oh lord. :shock: I am done, :lol: Dude, why does it matter? the stock system is still lacking. :D

Owned.

Sorry for chiming in so late, but we're (MagnaFlow) in the process of completing our cat-back as we speak. The car has been on and off our lifts for almost a full week getting test fit, and dyno'd. Once I get some more info I'll be sure to post it up here for you guys... stay tuned.

Nice!

when the final dyno slip is found please post it.

Werd I've been waiting for some more info on the Magnaflow system. keep us posted

We have already released our Full Cat Back Systems which are Emissions LEGAL if you add our High Flow Cat....

No pics! :doh: Who makes the cat? Is it California emissions OBD2 Smog legal?

All cat back systems are legal since they are installed after the catalytic converter and do not affect emissions testing. The only concerns in legality is whether the system complies and operates below the maximum sound decibel allowed in your area. adding a high flow cat would only make it 49 state legal as it would not be legal for usage in California (Not CARB certified).

luckily california is 2500 miles away and I don't have to worry about that. As for the maximum sound decibel if they allow all the old detriot muscle cars drive around setting off car alarams I think the tC should be fine.

Sorry for the mess up... it was late when I posted. We currently offer 3 options... Axle Back, Catback and a Full Exhaust System. We will be dynoing the Full Exhaust system within the next 2 weeks. The Full Exhaust kit will replace from the S-Pipe back and will require you to add a Highflow Cat to stay legal.

will the full exhaust have a test pipe or such to make it complete, and to become street legal the highflow cat has to be added in?

I hope that makes sense, but I can't think of how to reword that.

Here is an image of our Full Exhaust Kit without High Flow Cat

This image here shows the pipe that will be installed if you don't wish to have a High Flow Cat installed

Here is an image of our Axle Back Setup. You can clearly see that our Full Kit replaces the entire exhaust instead of the exisiting and our own Axleback Kits out there.

And finally here is an image of our system installed on the test car in which it was made on...

All the above exhaust kits show the exhaust with the Magnaflow muffler.

Thank you for all that info. Its greatly appretiated. All I do is await the final numbers. Hopefully one day I can work for an aftermarket automotive company... 1.5 more years and I'll finally have my bachleors as a ME. (at the moment doing total interior systems with lear corporation.... IP's aren't that interesting to me.)

Is the creative concepts exhaust all mandrel bent or are there some crush bends in there to. Also what mufflers are you using particulary from Dynomax? I would prefer the super turbo over like an ultra flow. I have a ultra flow on my tacoma which is also a 2.4L and it has gotten a lot louder over time, also it doesn't have enough back pressure and lost some torque

All of our kits are Mandrel bent 2.5" piping... no crush bends as you can see in the photos... I will get info on the dynomax muffler when my guy gets back in our office on Monday.

where is the cat? Who makes it? Magna flow muffler, nice! Gotta love the magna! Still where is the cat? Is it california smog legal? Need the info.

This post is pintless especially since I have a Turbo Kit! =)

As mentioned and as you can see on the site... You have to add the cat if you want it... Its an option we offer to customers...

Anyone else besides Magnaflow have dyno sheets to show the gains?

yeah I do. Need to post them up now, need to get in this. :D

whats the advantage to taking of the cat?

there are no advantages

just more noise/pollution, a nice CEL for you and everybody will hate you because of annoyance

Actually that is completly wrong. :eyebrow:

The secondary cat was placed there for government controled emissions, but since the first catalytic converter does all the work, and the motor only reads the first cat, the secondary is only there to clean up what is left, which is almost nothing anyway. The Check Engine Light does NOT come on when the secondary cat is removed, we have confirmed that here at PrecisionMuffler.com. Also the secondary cat has a honeycomb desin in it and brings the flow down considerably, but once it is removed and the motor has some more kick to it(Example:Cold air intake, turbo,header). You can feel a big difference, but just remember that the secondary cat is needed to pass visual inspection on smog.

I will be installing and dynoing the full kit with high flow cat and borla muffler from creativecompacts as soon as it arrives :)

I am still interested to know which company they used for the secondary catalytic converter. And if it is california smog legal.

I will find out for you tonight.

I will be getting the Magnaflow muffler instead of the Borla.

It will be shipping either tomorrow or the day after!

thank you. :D

He is getting that name for you and will post it :)

The catalytic converter is made by CarSound, they are a division of Magnaflow.

Is it the CA OBD II converter set-up? or just the OBD II set-up?

We are not using CA Complaint Convertors on our kits unless they are requested by the user. Since our company offers more options for the exhaust kits than any other company out there, we will make sure the exhaust kit fits the situation specific for the customer. If a customer wishes to use our full exhaust kit that requires a Cat Convertor, we will suggest to use the 43000 Series cat that is CARB legal. Be advised only our full kits mess with the Cat so CA users can still use our CATBACK or axleback kits without a problem

Also be advised, CreativeCompacts.Com offers all our kits in Stainless Steel as well as Aluminized.

Also be advised that the carsound 43000 series has not been cleared yet for the tC. But can still be purchased at www.precisionmuffler.com
