Can anyone give input as to which exhaust system is better, the richest sound, not "ricey" or honda civic-sounding, no whine etc.? Which one looks the best installed?

I haven't heard the TRD axleback, but I'm really partial to the Injen axleback. Magnaflow will be out w/ their sytem shortly.

I would say the Precision axleback, the trd sounds "ricey" IMO

The Injen has no 90 degree bends from the mounting point back. Will, have you heard the all fo the systems mentioned?

I havn't heard the injen

why bother with the axleback? just throw on a borla muffler or magnaflow muffler you'll get the same effect and save money. the axleback systems have no power gain.

i have the TRD on mine and it doesnt sound ricey at all and definatly opened up the exhaust, before it felt and sounded like it was struggling and after install opened it up. clean sound, not ricey at all

squirrel have you seen the injen it has a huge 90 in the piping it looks strange, also where is the percision sound on the web?

You have no idea what your talking about. The Injen and DC cat-backs have about a 6-8HP increase alone, and with a perforamnce CAI or Header install, will increase to an all around 20hp increase.

Any proof to your claims Rory?

well, Souljah347 was talking about axle back, NOT cat back. Big difference. Secondly, exhausts dont do much of anything besides make noise.

Thirdly there are no Injen Catbacks as of yet.

why are you in the penalty box?

The Injen axleback I saw and did the dB reading on had a 45 degree bend, but no 90. It came straight from the reear crossmember direct to the OEM exhaust cutout. I was there for the sound recording also.

I just looked at the pics I took a few months ago, and the bend doesn't look as pronounced as the production piece. I stand corrected. I was the one who's foot was on the gas pedal on the video.

I recently made an order for the Injen axleback, i belive it to be the best axleback soundwise design and quality. Its a straight through design so flow should be good. Like squirel said, the bends are mild . Combined with a downpipe and mendrel bent 2.25 tubing from header back it should yield at least 6 hp.

<<<<Precision Muffler-Magnaflow Catback>>

I have it and I love it, More Power Gain then the TRD and deeper then TRD..havent heard the Injen, should be nice!

http://www.injen.com/exhaust.html sounds nice not ricy at all compared to the competition. Once a header is added the exhaust note should change to a deeper sounding tone. :o

I would say the Precision axleback, the trd sounds "ricey" IMO

the TRD does not sound "ricey".... it is a clean deep tone.

On the tC there is no difference between a catback, and axel back. This is because, the axel is located at the cat. Anyway, I don't have any links to dyno reults on the injen right now. Do some net searches, and you can find some.

I would say the Precision axleback, the trd sounds "ricey" IMO

not from the inside of the car, but let someone else drive your car and see how it sounds

i have and its not ricey.
i think your not thinking of the same kinda rice sound. Debbie2go doesnt want the tin-can sound... and the trd i know for sure does not make that sound.

It depends on your taste in looks IMO. I think the TRD looks sexy!!!! Some people wonder why all that extra pipe was used. It was used to fill that area where the stock muffler goes. The Magnaflow looks like ___ as does the Injen.

Dont know if this is the only Magnaflow offered right now. Wow, UGLY!!!!

Not bad but nothing like the TRD looks.

From about 50 feet back the TRD is the best looking exhaust. As for sound, the TRD is the richest IMO. However it is loud for just an axle-back. My mom drives her car everday and has had nothing but good things to say about the TRD exhaust. I find myself walking outside just to watch and listen to her leave the house. I think the TRD sounds sexy extreme!!!!! It gets my vote.

Thanks for all the input. In CA, cat backs are prob. for the exhaust, cuz in the Sac valley, they have stink meters on freeways sometimes, that can measure the emmisons coming from the car.
And, as to just a muffler, where can I go to have one for the tC installed? I went to a muffler shop in Rancho Cordova, and I was told that due to the position of the muffler, it would cost $320, I think that was just to route the muffler and pipe to make it fit. Ouch. For that price, I want the whole system.

hey dumbass read what i wrote AXLEBACK not cat-back.

axlebacks do nothing but make noise. they show at most 3hp increase at the crank.... so thats like .3 hp tops at the wheels.

Cat-backs shouldnt be a problem in Cali. As long as the cat itslef isnt touched/modded in any way you should be legal.

Also that shop, are you sure that wasnt $320 for a full cat-back??? $320 for installing a muffler is hella expensive!!!! I know a place that charges $30-$40 for muffler installs.
To tell you the truth, just wait a little longer for some exhaust systems to come out. Its just a matter of time before other companies make performance mods for the tC.

you don't need to redo the exhaust system on alot of new "tuner" cars because cars are getting more and more efficient

I would like to see a dyno on that or some kinda proof, b/c even if the TRD axleback did make some power the TRD cat-back would still make that plus more.

wrong
trd axleback on the celica gts got more to the wheels than any other catback


Cat-backs for the Celicas are axle-backs. Pretty much all of them just replace from the rear axles and back. Celicas gain more power with no exhaust.
Axle-backs should gain any power. Its like adding a muffler on a Civic. If they do gain power then.......uhhhh good for it.

wrong
trd axleback on the celica gts got more to the wheels than any other catback

you don't need to redo the exhaust system on alot of new "tuner" cars because cars are getting more and more efficient

The celica and the tC are two different vehicles or else the celica exhaust system would fit on thew tC. The axle back on the tC will only give you a HP gain of about 2HP. Adding a CAI does help it out too.

The Magnaflow looks like ___ as does the Injen. Dont know if this is the only Magnaflow offered right now. Wow, UGLY!!!!http://www.racingsolution.com/Images%5Ctc_exhaust3.jpg

The correct magnaflow for a perfect tone and fitment would be the axle back designed by us here at Precisionmuffler.com. A perfect design for the right amount of backpressure and volume control for a Precision Tone!
http://www.precisionmuffler.com/2e6902c0.jpg
And of course I know that magnaflow is going to come out with their own cat back too. So be that as it may, if you are going to add more power to the tC than I recomend a catback. But if you just want sound than the axle back may be the best way to go. Having a catback with not enough power to help it along will just be a waste of time. I hope that this helps with any question to purchasing a catback or an axle back. 8)

ask an exhaust guy the axleback gains are worthless. with all the restriction from the cats an axleback really don't do much. stylis says 2hp, is that at the crank or the wheels? anyway he as alot of experience with exhausts, he does it for a living. i'd like to know what your creditentals (spelling) are. and he's not the only one that says it btw, my stepfather owns a custom shop and he said the exact same thing.

I would say the Precision axleback, the trd sounds "ricey" IMO

the TRD does not sound "ricey".... it is a clean deep tone.

nope its ricey, to be honest i havent heard the injen but ive heard trd and precision and precision cat back added alot of power actually on the dino, the dino showed 140hp @ the wheels and 138lbs/ft at the wheels (might be the other way but basically 140 140) and no header or intake or ne really option (besides supercharger) has added that much from what the companies have showed on the dino... and ya alot of you are like well you only say that cuz ur sponsored but if you ask neone in my crew (team NVS) they have asked me that if i honestly had a choice which would i chose... i said the magnaflow from precision honest to god.

gabe does a good job, all of his sound sweet

Horsepower gains can be talked about over and over again. Everyone has an opinion to what they think is best, but when someone posts the dyno sheets, then there is no arguing.

let me come at it like this...

unless you do some type of forced induction, cat-back or axel-back horse power gain is a silly thing to think about. bottom-line is...YOURE NOT GOING TO GO VERY FAST. i have an injen intake, dc headers, and injen axel back...and i did those mods cause i wanted a certain sound and to attempt to make the little 4banger a bit more effeicient.

you all are talking about horsepower like you think youre going to get some where FAST in the thing...pls...if thats the case, you should have got another car.

for what its worth, gabe at precision or ken at michael's will be able to take care of you, and you'll know it was done RIGHT.

I am going to dyno the tC we sponcered again, but tomorrow I will have to post up the dyno numbers we did get. They were good numbers but we want more. :D

gabe does a good job, all of his sound sweet Thank you boombox. Much appreciated.

stylis says 2hp, is that at the crank or the wheels?
To the crank :( To the wheels is 1hp gain, if that. I really hate to say that, but I am here to help out the scion folk. 8)

^^^Werd!^^^

Like I stated in another post, these are 108hp commute type cars, with the exception of the tC which has the Camry motor.

These are not EVO VIII MRs, or Ford GTs, or Corvettes.

ive owned all of those... they arent that fast

ive owned all of those... they arent that fast


I support that because Ive beatin all of those. In my Mx6

The Ford GT has been released yet. There is a recall on the front upper control arm failing.

ive owned all of those... they arent that fast


I support that because Ive beatin all of those. In my Mx6


:rofl: ...only in ScionLife... :rofl:

For that price get the system. Believe me that price is terrible, and the tC does have an odd location for its muffler, which isn't norm to a lot of other cars like civics, I think.

ive owned all of those... they arent that fast


I support that because Ive beatin all of those. In my Mx6

you've beaten a ford gt (not a mustang gt) and a vette and a evo mr.... well to be fair u probably raced stock ones... i dought the gt one... whats your 1/4 mile?

and you have owned a gt?

no i was being sarcastic, i just think its funny that , the guys ego thinks he can beat all those in an 89 mx6.... y is he posted on scion life bout his mx6? the fastest car ive owned was a 92 eclipse gsx awd turbo that ran a 14.8 1/4mile stock... thats it

does anybody have dyno sheets of the tc with the trd exhaust???

people are knocking axle backs before seeing dynosheets which i find funny because the same happened with the celica even if the celica is a "totally diffrent animal"

yea but why are people knocking the axle back when the axle back is the same thing as a cat back on the tC.

i like axlebacks personally, endlessracingz do some research before posting man your inaccurate. We dont have a cat at the axle, its all the way in the front after the primary by the front wheels. And from the R&D done it looks like a less restrictive "cat back" should yield nice gains on the tc.

I am just going by what I've been told by companies. So now I am just completely confused at to where the 2nd cat is on the car.

axle back systems are going to be a bolt on system. A cat back will have to be clamped or welded on after the secondary cat. Thats the difference.

if you where to get a full exhaust system one that does not use the 2nd cat for track use of course ;) that would bolt up right to the header?

A full exhaust system would mean, removing everything. The first cat is molded together with the manifold. So you would have to get a header and than build a full system. If you don't want to remove the manifold,than you could go with the precisionmuffler.com cat back.

I was talking about the following system from the thread titled "Exhuast"

Here is an image of our Full Exhaust Kit without High Flow Cat
http://www.clubsciontc.com/files/tc_catback_full_mag_detail.gif

This image here shows the pipe that will be installed if you don't wish to have a High Flow Cat installed
http://www.clubsciontc.com/files/tc_frontpipe_nocat_detail.gif

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.
http://www.clubsciontc.com/files/tc_axelassem_mag_detail.gif

And finally here is an image of our system installed on the test car in which it was made on...
http://www.clubsciontc.com/files/tc_axelassem_mag_detail.gif

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

It seems to me the full exhuast system shown here would bolt right up and not need the welding and what not. Or am I wrong?

^^^Looks like a direct bolt in to me. ^^^

Looks like a system to try out on the track.

But then again, I'm no exhaust guru.

yes acasanova is correct, there are actually 2 cats on the tC one that is directly mounted to the header (unfortunately) and one that is about 14 inches after that before the resignator... and axel back replaces everything from that first cat back

I knew there was one in the header but I had thought that the 2nd cat was at the axle, therefore an axle back is equivalent to the cat back. According to Injen's website for their cat-back exhaust they have in parenthesiss axleback.

So Axle back is considered everything from the headers and back? Because thats how it seems you states it SOILWORK_tC or did I miss interpret it?

As for the cat-back it is like any other cars cat back, from the cat physically under the car back.

This whole dabble has made me sound like some unitelligent car modifier when I was just confused about the Scion tC's setup. I do not own one yet and am trying to learn as much as I can about them before I purchase one. I have previously owned Eagle Talon AWD Tsi capable of running in the 13's which isn't that fast but did require modification.

Thanks for helping me clear this stuff up.

[It seems to me the full exhuast system shown here would bolt right up and not need the welding and what not. Or am I wrong?

nope there is still one pipe that comes down from the thermal reactor manifold. It goes underneath the motor, and than attaches to the exhaust system that you are showing. So the exhaust system you are showing is a cat back, not a complete replacement exhaust system.

catback from the first cat seen under the car and not the one in the header. Alright I think I have a hold of everything.

i have to say one thing u r wrong about..... talon awd tsi (as the eclipse gsx) are capable of 9's... as far as ive seen i had a friend thats 93 eagle talon tsi awd ran a 9.87 1/4.... could not believe how fast it was!

Well, I did it, I bought a TRD exhaust from Scionpartspeople.com, cost $360, including shipping, got here in a few days, now if it would only stop snowing, so I can get out of the driveway, and have it put on!!!

Thats ok, I am always happy to help out a fellow scion owner. Thats what I am here for. :D

Yup, that's what I'm doing, helping out another Scion owner. And making sure the info he gets is not misleading, and gets the most for his money.

Welcome to the club than, its good to see that. Have your friend email me for more details on the catback for the tC. Colin and I have been working hard on this system. :)
