Today I finished installing a A & R Baffel kit on my 1198's exhaust. I cant quite afford a aftermarket exhaust yet. OMG does it sound amazing! It sounds like a my bike just went through puberty and its voice deepened. For a $115 I can't complain. It runs like a champ. No back firing or sputtering with stock ECU. I do plan to get a Nemisis soon though. Throttle response is better. I think I might have gained a few ponies. It picks up the front wheel in second at 4,000 rpm no prob. before it was more like 5,500. If your a little handy and dont have the cash for an aftermarket exhaust, give www.aandrmotorsport.com a chance. It took me about 6 hours of taking my time drinking a few beers and it got done. Looks great. Will post pics soon. Any ride longer than 5 miles you should wear earplugs. I might just go and start it up now to listen to it, sounds so sweet!!!
