I'm runnin a dynomax camaro muffler, and it has a nice low rumbly sound.
I'll trade u straight up for ur SLP muffler
My Dynomax has the SLP dual tips on it also.
One other thing, with replacing the CAT with the str8 thru muffler, will ur car still pass emissions tests?? (if u have them) and what does that do, just make ur exhaust louder??
