Nice pipe

Rulon in UT – Machine this part was bought for: 2011 HONDA CRF50F

Comments On May 10, 2013:Did not notice a big power gain but a lot of weight difference from the stock and that alone made a huge difference.

FMF Power Core IV S/A

Karl in NV

Comments On Feb 06, 2013:I have installed and run lots of different exhaust systems on my bikes, some of them way more expensive, but none of them fit as nice, installed easier or gave any more performance. Best pipe for the money for sure.

Great exhaust

Damian in CO

Comments On Mar 04, 2011:We were running a stock pipe on this quad and having trouble with a few hills at the sand dunes. This year the extra power and great sound were awsome.

Fits like a glove

Comments On Feb 08, 2011:Put this can on a Raptor 90. The fit was excellent, and the sound is very good as well. Gives the little Raptor extra grunt as well.
