Yes, Another Exhaust Question.....
I have brand new GM cats as I just brought the car in with codes and the dealer replaced both of them under warranty.
So, BBK shorty's, the factory cats, SLP's larger diameter y-pipe (yes, it will rub some more), and then what cat back is the question.
I've got some aftermarket/stock set up in there now with a Flowmaster muffler that is pretty old. Hate the sound of it and from what I read, the FM is the worst flowing.
Which CB is best for flow purposes, don't want SLP LM (too loud), and will not break the back (Borla, Corsa, are out)?
Mods are SLP lid, BBK 80TB and BBK SSI intake, deleted air system.
Thanks,
Jon
