i was wondering how many people have this and what thier experience has been. according to a couple sources, this will give more hp than any other aftermarket exhaust (when properly jetted). anyone heard otherwise? Thanks.

also, are those dynojet kits any good? or should i just look for original honda parts when re-jetting? the exhaust comes with "tips", do they meen the main jets, pilot or both? do i really need a new needle? thanks.

 

Dont waiste the money on a dyno jet kit... Just get the jets and needle seperately.... I made the mistake of buying the dyno jet kit for like 45bucks when I couldhave just gone to the local dealer and picked up a better needle and better jets for maybe 20$ total... I am running 52 pilot jet 185 main jet and a white brothers needle... Once I changed from the dyno jet kit I would tell the difference plus it doesnt come with the pilot jet which is key for 1/4 - 3/4 throttle performance....

For the exhaust I havent heard much I am running a FMF Factory 4 Titanium exhaust with powerbomb titanium header.... I am happy with the results, great torque.... Dont for get about the CAM if you lookin for more power HRC Cam is a must..
