Arrow exhaust on and remaped today. I tell you this made such a difference. First the comfort level is night and day now. The stock exhaust caused my leg to bend outward in a painful fashion. The new exhaust hugs the cycle and I can get my knees on the tank. Loosing about 10 pounds from stock v/s this exhaust was a nice benefit too. The sound with the baffle in is great. Take the baffle out it sounds like any straight pipe twin. The power increase feels good..it could just be the noise causing me to twist the throttle a bit more..lol.. Over all very happy that I moved from the KLR to this. Night and day with build quality and hey no more oil usage!
