We've had a number of calls for mufflers for the new chassis so that was the first thing we set out building. The result is a super light, quiet muffler that we were able to make HP with! The muffler gained 1.9 HP over stock (no jetting changes) and is much lighter than the stock one. 157.9 @ 8100 and 102.4 @ 8000 and 8100. It has a trail friendly sound, 'throatier' than stock but not anywhere close to 'get you in trouble' loud. Looking to drop weight? This muffler is only 7.5 lbs!! Ceramic chrome coating will take an additional 1-2 weeks. NOW IN STOCK!!!!
