Which one?

[breakers97]

I'm getting a cat-back exhaust system, but I don't know which one is good for my 02 GTS. I narrow it down to 3 which are Thermal, Greddy, or TRD? what do you guys think?

Try the Search Function and type in exhaust. You

Both the TRD and Greddy exhausts are axle back systems. Out of the three you listed, thermal is the only cat back system, so if you are looking for a cat back, I would say get the thermal.
