lots of threads. find the one with the youtube link. has video showing 6 different exhausts back to back. I have an Ida, very similar to my neighbor with the Stillen. I can't really tell them apart.
What is the best aftermarket exhaust system?
I want to to give my GT the sound it deserves.
Mine!! Ask anyone at Rally 6....
(or Rally IV for that matter....)
The best sounding exhaust system is not aftermarket; FRPP Rear Exit Headers!
