At last, a combination of our best flap in what is now the easiest installation ever. Whether your tired of "Clanking" metal flaps or just can't believe you have to cut out and braze in a new butterfly style flap; there finally is a solution.

No cutting or welding, this unit is designed to merely slip over the inlet side of your existing 4" exhaust tip, and is held or clamped into place by your existing exhaust hose.

Definitely one of the best new conceived part of the year.
