Im planning on buying a rossier exhaust and spark arrestor for my 06 TRX450er and i was wondering if i should get the rossier jet kit to or if i should just go with the dynojet. I have a hc stage 2 cam and will have an open airbox. thanks

Dynojet kits work awsome in the z-400's and raptor 660's but in all the 450's using the OEM kehien jet is the best way to go. I have jetting specs listed on the Rossier Engineering web site. Click on the instuctions and they are on the bottom of the page.

Thanks Joe

so its better to get oem jets then to get the rossier jet kit or is the rossier jet kit oem jets

My jet kits are sold with kehien jets and with OEM needles

alright thanks for the help

how bout lrd's jet kit? Sorry just wandering because i can get them at my dads shop, was planning on DJ but not now.

where's the best place to get a rossier pipe? Straight throught rossiers website?

i am tossing around the idea of getting a rossier pipe and i was wondering if the fmf jet kit would work and just wondering what jet i should run i have a twin air filter with no air box lid just a outerwears cover on top.
