Sorry to rain on your parade, but these mufflers are downright horrible. My buddy had them on his sbc. Even with hooker headers, they sounded funny. Not good, not bad, just funny.
To begin with, the first pair rusted out within about 2 months, so he got them replaced. The second pair has horrible welds on the muffler (not from the muffler shop) and the mufflers are beginning to rust again.
I'd recommend something else, what are the muffler(s) going on? I'd look into magnaflow, borla, and spintech
