Q about slip-on

Like you said, we removed the muffler/exhaust tip and the "under-muffler" on muffler/converter combo. Anyway, before anyone breaks out a fucking drill, they should first determine what model slip-on they have (wasn't mentioned in OP) and give Yoshimura a call!

All '06+ new bodies have a cat.
