which curtis sparks exhaust?????

[benard_80]

heys i have a 05 trx 450r and i have the HRC kit. I looking into getting a full curtis sparks exhuast. Does anybody have the t-4 and does it suit the 450r well. Also will i have to re jet my carb or will it be ok to just keep running the 185 main jet from the hrc kit. thanks benard_80

get the sparks big core it runs around 450 bux "pm me if u dont know where to get it". if you have the complete pipe and a airfilter i recommend taking off the air box lid and running a 180-185 jet with some adjust on ther/ful screw

if u leave the air box lid on im not sure which jets to use but someone will know on here

I bought mine and they told me it was fine with the HRC's jetting. I did take the hrc's lid off and now I had to adjust the fuel air screw.

If you have the complete hrc installed and plan to keep the hrc lid on you should be good with either sparks big core or standard core. Just to let you know the big core is a bit louder, although both are pretty loud.
