The megabomb was a great addition to the 4.1 muffler. I little deeper tone over stock and muffler. Added a little bottom end grunt and pull, and the whole system together really Gives the bike a better and smoother pull all the way through the power curve.Read All Reviews

I have the full system and as soon as I put it on I could tell a power difference. It really opened up the top end. The look of it makes it even better. I did however have a popping noise in the cold if I am letting the motor brake for me. Awesome pipe all aroundRead All Reviews

I needed a spark arrestor and I purchased this one since the aluminum one was on back order and as always, sound is great and not too loud and provides excellent power throughout. I never rode the bike with the stock muffler so I cannot compare it but FMF always delivers power gains.Read All Reviews
