Exhaust system
I read from magazines that the stock exhaust system on the GTS is pretty highflow already, so any aftermarket system usually doesn't give you much performance increase, just more noise. So I was just wondering, do you gain much from doing a full catback, or is a rear section replacement sufficient?

I haven't heard anyone's car with the TRD exhaust yet, but its suppose to be quite streetable and fairly quiet/moderate in sound/noise right?

The GTS Exhaust system was designed well, but there are actually better. Which magazines did you see that in?

Celiwhite pretty much wrote a good one, I agree to wait for TPR. I don't think their product will be much better than TRD though, so if you want it done now go with TRD.

i believe the TPR one, when combined with the TPR CAI, makes somewhere in the neighborhood of 33whp at lift

33whp @ lift?! Sounds too good to be true...wish it is so! smile

According to these test results from Turbo Magazine, I can only see at most a 5-6HP gains at the wheels from an exhaust, I think the TRD one had the strongest numbers. Combine that with an expected 8HP to the wheels from a CAI, I can only see a 13-15hp @ the wheels gain max. So I dunno how 33 is possible?

well like the TRD the tpr only gets that high of a gain at one rpm one lil spike on the dyno

high numbers mean nothing its the area under the line thats important
