how much horsepower does it put out???

Well, it supposedly adds around 6hp but thats an estimate.

Check out Sportcompact Car's review... their car had the TRD exhause and the AEM cold air intake which isn't avalable yet.

They got 152 wheel horsepower where the stock is an estimated 140 i believe.

Please excuse the inaccuracies... just lettin ya know.

i dunno, but it sure does sound great! :D

i hate that i cant decide........... injen, borla or TRD

Any axleback you get is not going to give you much if any gains at all. I got the TRD only because I liked how the full stainless steel muffler looked it sounds great too, but if you're looking for gains wait for someone to come out with a full catback system

i dont care about gain that much on the tC. +4-8 HP on an exhaust wont make it much faster.

i cant beleive nobody has came out with a catback for this car yet...

go into toyotas parts department ask them about the CAI the guy told me while i was there the other day that i could order the aem cold air through them only but they wanted $330 but since i got my connections i'm only gonna pay what they do but all i need in the money

TRD really just adds sound, not any performance you will notice

i've noticed a bit of performance. you cant say it does not add "any"

it adds maybe 1hp if that to the wheels... so yeah, it doesn't really add any :P

show me

show me the dyno before the exhaust and after
again nothing you will notice
your bit of performance is probably all in you mind

i just put in the trd and weapon r intake/ram air kit, and i think that not only do they sound awesome together, but it definitely adds some power. i dunno if the trd exhaust alone does that much that it'd be noticeable, but with an intake, it does something.

only a month old :clap:

The reason that I am selling it is so I can get struts that I should've bought instead of the exhaust.....ABSOLUTELY NOTHING WRONG WITH THE EXHAUST....i just broke it in for ya!
