Magnaflow muffler???
Found this clip on youtube and it actually doesnt sound that bad for an 800 efi, it sounds a little deeper than most of the others I've heard online. Check it out:
Does anyone have any clue as to the stock diameter of the factory exhaust pipe? From the info I've found on that guys swap it seems he used a magnaflow muffler with a 2 1/4" inlet/outlet and I'm just wondering if that's the same size as the stock pipe. For the cost of it, $72 bucks for the muffler, I think I'm going to give it a try! Thoughts?
Joe.
