Good exhaust for the price and nice to have another exhaust option on the market. Not the best sounding out there but does add a little noise with the quiet core removed, as well as a little low end power on my yz450f. Does have some rubbing issues on the tire and is very long which makes the bike look a little dated over the factory "shorty" silencer. Good for the money but if I could do it over I would probably save a little longer and go for an FMF.Read All Reviews

I noticed on the road the transition through the power band is very smooth. Holding high rpms at consistent speeds is much easier. Combined with a Steahly Flywheel weight the bike launches from a dead stop which is handy when trying to get over large logs on tight trails. I would not discourage anyone from buying the Gnarly pipe, but get the flywheel weight as well.Read All Reviews

Bought this so I could ride on local trails. Installation was a snap, took me less than an hour to get the part installed. Just make sure you follow the directions and have the required tools, I recommend having a heat gun or torch on hand to heat up the stock silencer to loosen up the sealant used on the stock end cap. Bike sounds a little louder than with the stock end cap but it's barely noticeable. Part looks and feels high quality and mine was black, apparently the color varies on application.Read All Reviews

By far best value for what you get. Improved performance all around especially pairing with the fmf gold series gnarly woods pipe. Less than 5 minute install. Sounds and looks great and came to my door as expected. No disappointments here ! Thanks Rocky Mountain atv/mc !!!Read All Reviews
