I have a question, I have the Bisson Custom Mufflers wrap around pitts muffler for my MVVS 45. To keep from butchering up the cowl was thinking of trimming the down tubes on the muffler then adding extensions and a couple elbows to direct the exhaust through the canister tunnel and out the bottom of the fuse. And not have to cut the bottom of the cowl.
My question is this, how will this effect the performance? I do not want to adversely effect the power and do not really want to cut the cowl, as it appears I will have to cut a portion of the mounting ring if I exit the bottom of the cowl as one normally would.
