never heard of anybody taking a streetbike exhaust, and putting it on a quad. Have you run it up against a regular atv performance exhaust? how does it compare?

rips.Wouldn't have thought such a big difference.First time on the track scared me like it was new.Over it now.But I had to pull over and shift to 1st to know what gear I was in for sure.It puklled like a different gear but at the same speed.Maybe trx450r's just need a pipe.Got a date with a dyno this Fri.Hit you back /stock & moded next week,pictures too.Ideas are cool, finding people to make them real is pretty tough.
