Important Exhaust Notes:• Note: With any new exhaust, we recommend changes to carburetor jetting or use of an aftermarket fuel injection control module.• There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Blueing is caused by tuning characteristics, cam timing, carburetor jetting, overheating, etc. and is not caused by defective manufacturing. No refunds on exhaust pipes once motorcycle is started unless there’s a manufacturer’s defect.• Flanges and retaining rings are not included with most aftermarket exhaust for 1984-2013 Evolution and Twin Cam models. Re-use your existing hardware, or purchase replacement hardware.(SS550-0664)

Reviews
Nice MK45's
Got these puppies on today and love the sound. They put out a deeper tone than standard mufflers but not any louder. Perfect for early morning starts and keeping 5-0 away. The Db reducers made no difference at idle (to my ears anyway). Have not ridden with the Db reducers out because I like the mellow sound as it is, and they growl when you give it some wrist. My neighbours don't even know I got mufflers. Yay. Big thumbs up to S&S for quality and easyr for great service. CheersBy: Roger R on 26 January 2020
