Fmf 4.1 slip-on dual

just installed onto my crf 450r motosport hooked me up with some plugs as well for washing the bike free of charge. I think cause there not stated in the fmf parts supplied so that's awesome thanks motosport!!! the sound is amazing has a better tone vs stock completely opened it up standing next to the bike you can fell the power more than stock just like fmf states this is a great upgrade and best of all fmf is made in america

Good purchase

Noticeable power gains in the low to mid range power. Have it on 2015 Honda crf450. Do all single track trail riding and hillclimbs. Happy with the purchase.

A: As long as you have the correct year & model bike selected it should. I purchased this for my 17’ crf450r and it fit my stock header.

Q: Are these supposed to come with reducers or clamps to go on the stock header? I received this slip on and attempted to install on my stock header but realized I needed some other hardware.
