Any recommendations which one to go with? My cats went bad 2 mos ago on my bassani catted x pipe replaced them with flowmastet hi flow cats already gone bad after contacting LMR they said those cats are not designed for blown cars and but wasn't told that when I ordered them. Any recommendations?

I was just talking about the cats since you said you had been swapping out cats. I'm pretty sure kooks sells some high flow cats that can handle boost. If you want a whole new x then I'd get a magnaflow catted x.

Ok thanks I'll check them out. If I get cats I'm gonna have to get them welded in by the time I pay for cats and labor I can just buy new x pipe and bolt it in myself will cost about the same.

You might want to check your tune. Perhaps the safety features for keeping the cats cool are shut off or too high of a temp. Once the cats get hot the computer is supposed to richen the air fuel in order to keep it at a safe operating temp.
