Hi Jim, it sounds like a straight pipe back to one muffler is what you are recommending to avoid the differential back pressure from two forward mounted mufflers. Is that what you have found works best?

Jerry,
Having one muffler is a good idea, however not all coaches can be converted
.
We supply a 16 ga, SS muffler with lifetime warrenty.
Never use the cheap auto muffler. Use a TRUCK muffler.
