Dude, lay off it and do a search.

 

My buddy just the gytr exhaust for his yfz-450 and he raced a stock yfz-450 and the only improvment was low end. He also said topend was the same and was not pulling on the stocker. N e how i talked to yoshimura and they said with there exhaust they dyno'ed a yfz-450 in a 43 hp i think could of been 44hp. I was like DAM

 

ty for all the great tips

 

I have an fmf q pipe. I took the baffle out and since I rejetted, the difference is awesome!!! Good luck, opinions are like belly buttons ( I was being polite). When I start raciing, hopefulle next year, I'm looking at getting a new pipe anyway. Prolly a YOSHI.

 

does anyone know where i can buy the TC racing pipe? i tried the tcracing website, but my comp's all jewed up and i couldnt download it. i heard it on this womens yfz at the cny powersports drags (cortland, ny) the other day, and it looked and sounded awesome. she had nothing but good stuff to say about it, so any info would def be appreciated!
