Celica Forums General Discussion Exterior TRD exhaust numbers for GT

i am thinking about getting a trd exhaust for my cel and i was wandering what the power gains a for the gt are and also is it a cat back system from the headers back or is it just the muffler and tip?

Far as I know, it starts just before your rear wheels, includes the pipe form that point, muffler & the tip.

You gain maybe 1 horsepower, but it sounds cool.

^^^^^^have you lost ur nuts and become a woman first of all yea its a bolt on easy to install and some company's call it a cat back almost same thing just no welding etc...and the gains are about 8hp check out dyno threads ...1hp

wooo ! rock! yeah! 8 hp at really high up rpms !!!! woooo!! wait, where did my lower end torque go.. shit!

how is it at all the same thing with just no welding? TRD exhaust is just an axle back that replaces the muffler and tip. i used to have the TRD exhaust and i was dissapointed with it. now i have kazuma (a cat back exhaust) and ill tell you that when it comes to Performance there is no comparing the kazuma and TRD. with Intake and TRD i ran 15.9, with Intake and kazuma i ran 15.59.

The stock muffler connects to the main pipe just before the rear axle on the engine side. The TRD would obviously start the same place. And yes it is an easy bolt on mod.

8HP according to manufacturers, but that is BS. Third party (meaning people with nothing to gain or loose) dynos say about 1 horse. I would say the weight savings are probably pretty good though & the sound is cool.

Yah maybe 8 after you have done cold air, headers, Turbo & cat converter ... and its restricting flow.

If you believe all the horsepower ratings for the bolt on mods, you can get about 200 more hp without Turbo ... smoke crack, its a better dillusion.

Here, this is an example of a stock GT with TRD exhaust & cold air Intake. It compares AEM with Injen cold air. Its third party & impartial.

Yippee ... $1,000 for 2HP ...
