Exhaust set up....WOULD THIS JUST BE CRAZY???????

5 posts in this topic

Ok, me and EX2Stroker were trying out each others bikes this weekend and I need to change something. My bikes got good suspension, but rides like a honda. He's got a Thunder alley on a all stock bike with 15/50. His pulls like mad. Has anyone put a Thunder Alley pipe with a FMF power bomb. Would this just be suicide??? I'm thinking of just getting a power bomb right now and ordering a thunder alley in the winter. What do you guys think.

P.S. I wonder what the dyno would show with this type of set up????

If you felt the difference between our two bikes, you would think so. :awww:

Maybe yours dont run right then?? :thumbsup:

Honestly, probably will be hardly noticable on a dyno...the stock exhaust on the yamahas are already pretty good and while you may gain a single...maybe 2 horsepower , its most likely to be down lower. Dont expect a 10 HP increace everywhere like your sounding! :lol:

All else being equal, check the jetting and valve clearance specs. If you are feeling that much difference, and the gearing on the bikes is the same (hint hint) then either one being off would cause a lack of power.
