TTS 1-3/4" here with their y-pipe and cats. Same set-up GMMG uses on their phase 3 cars. Fit and finish is worth the price tag.

Looking to bypass the cats with some offroad pipes to get that little extra hp.

 

Running the SLP long tubes and cats with the hooker cat back and it's awesome check out Ls1 sound for all the different set ups you wont be disapointed with my sewt up no hitting of floor at all and sounds great my ride is the 2001 ss
