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
My bud bought this and it sounds great and has a noticable power change.
FMF makes good quality exhausts
Put on full system and love the sound and power it provides.
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.
This exhaust is the sound of instant satisfaction!
