Right now I have a stock muffler and 2r tip. I’ve been thinking of getting a new slipon. I’ve seen a lot of opinions on Barker and two bros but cost and noise is a concern. HONESTLY….. Will a slip on make that much of a difference? I’ve been a licensed Aircraft mechanic for 35 years and know my way around a car or truck BUT…….I’m very new to the ATV game. I’ve installed headers, low flow mufflers etc. on a few different types of vehicles. A lot of noise, (a cool sound when I was younger) but as far a HP and fuel gains???? just want to know…. Is it worth the money.
