TSP Catted-Y question
I just want carsound cats and an aftermarket Y for a GMMG, I think it makes the GMMG sound a lot better! No one does Mandrel bends around here, so I have to go with a catted-Y, ready to install.
Thanks guys!
those are the ones I was talking about, their random tech, which are still good cats, but the gains really arnt worth 500 dollars
I'll have to give it some thought.
I think even by putting that Random Tech catted-Y on, they could fail me.
I really cant decide, but I want my GMMG louder than stock, somehow
