A must have upgrade for a 2014 Yamaha XT250

Purchased this slip on muffler for my 2014 Yamaha XT250 and I could not be more pleased. It was a perfect fit, only took around 10 minutes to install. Sound is excellent and I got a noticeable difference in torque in second and third gear. I would definitely recommend this muffler!!

The best thing about this pipe with a gold fatty on a CR125r is it drastically increased bottom end and smoothed the mid-top end of the powerband.

DRZ400S . . . Bombs away!!!

Easy to install and a very noticeable difference with the bottom end power. Not having a heat shield I thought might pose a problem, however I haven't even noticed that it's gone until I get off the bike. Best upgrade so far for the money.

Great Product

This product fit my grandson's 2014 Honda CRF70 perfect. After I took off the stock pipe, it gave the bike at least 8mph. It sounds great too. I would suggest it for anyone to help their performance on their bike.
