GMMG Y-pipe/Cats question
I noticed on LS1sounds.com a car with the SLP Y-pipe and aftermarket cats sounds a lot better than the completely stock cars with the GMMG installed.
I'm just curious, should I buy aftermarket cats and an SLP Y for mine? would it be worth it or should I just do the Y pipe???
I'm trying to figure out what makes that car sound so much better, the SLP Y pipe or the cats? ...or the combination of the two?
Thanks guys!
If you get Long Tubes and a catted y with a GMMG, then you have what I consider to be the best sounding car on the street.
