[Thomas92]

i have now a 250r with a ct pipe and i have also a ct310
but what's best ct310 with ct pipe
or esr 310 or 330 with an other pipe?
what's best 310 or 330?

What kind of riding do you want to do? What kind of porting does your 310 currently have? Porting/pipe/carb/intake, all go hand in hand when trying to setup your motor.

I personaly would recomend to order an unported ESR 310 kit along with a ESR trx5 pipe, and then have a someone do a port job for your style riding (such as our site sponsor FloTek)

trust me generaly esr does better porting than ct ..ct is one of the worst ,with duncan and trinity i na close second
