I have a muffler that I have built for a a sport boat. Problem is, it works to well. The boat is way to quiet. Some how I think i have actually got the dimensions correct to cancel out most of the desirable exhaust note. I have look around and cannot find anywher to get any answer on what I should change. I though that maybe someone here might know. It is a v8 engine and the exhaust goes into a 6" dia tube that is 3 ft long that is mounted accross the transom of the boat. It has two inlets that are 4" in dia and are 28" apart c to c. The oultlets are 4" dia alos and are centerd on the tube and are 12" apart.They are all fluch mounted. Have I fluked out and got the distancese so that the exhaust waves are colliding and cancelling each other out? I can shorten the inlet ends of the tube 2" and the outlets 4" if needed. Or I can add length also.Mark
