This past week I was able to meet joe at little sahara ok. I run the dyno there and have sold a lot of rossi's in the past year. I have had great luck with these exhaust..... no returns on broken exhaust and they always bolt up nicely. Across the board from ltz, to yfz, to ds 450 etc.... these exhaust put out great rideable power curves. It has been a pleasure doing buisiness with you! Anytime anyone is at little sahara and wants a great fit and finish exhaust at a truly reasonable price stop in and check out the rossier products. mike d
