I took a stock X440 muffler and adapted it to a stock "bread box" headpipe. I plan on running a blaze map in this quad. I have had good luck shortening the stock breadbox, but it is basicall an empty square box hanging on the side of the bike. I have several of these mufflers and thought I'd put them to good use.
So, any opinions on this?? I let you know how it sounds and works in a few days.
