About Us

Rossier Engineering

 Welcome to Rossier Engineering Exhaust's product page. This company first opened it's doors in 1991. Primarily a watercraft and dirt bike performance shop, we enjoyed a great deal of success during the watercraft racing boom of the 90's. As that market declined, we noticed the popularity of the burgeoning ATV racing scene. We followed the trend, and switched our operation over to 4-stroke development, concentrating on the 450 race quad segment. After brief retirement the exhaust part of the company has made a return and is now making exhausts for yfz 450r's , Raptor 700,kfx450r,ltr450,ltz400 and trx450r's. Please feel free to call with any questions- (970)-391-8675
