Re: Exhausted!

Welcome to the forum twelveport!! :2tup:

You're absolutely right, it has the dual exhaust pipes at the cylinder because of the two exhaust valves. And I assume it reduces to less than an inch at the end of the muffler, um, well, to muffle the sound.

People here have tried to imitate the Harley and Ducati/Moto Guzzi sounds by drilling two large holes in the muffler plate (at 22.5° and 90°, respectively) but that somehow never works out as planned, no idea why.

PS - twelveport - I can't keep from guessing - you are riding a three cylinder with four valves each cylinder (Triumph?), or a four cylinder with three valves each (no clue), right?
