Questions & Answers

  • Hi, I purchased one of these headers awhile back and really like it. I was wondering if the perforated core baffle will fit ? MAC Performance 4-1 Competition Baffle Into Canister Style Mufflers 009-1319. We ran the bike at the BUBB event last August and went 127.6. Thanks, Tom Perry

    Yes, the perforated core for canister mufflers, should fit that system fine.
