ok, i think i received false info about Aaen or whatever making a pipe for a 250R, but i'm still looking for a pipe/silencer combo for MX racing. I have narrowed my choices to ESR, Sparks, LRD, Paul Turner, or FMF rev pipe. Any suggestions or if anyone knows about better pipes than these. Oh yeah and i would like to mention that my 250R has a 310 full race ported cylinder that runs on 110 race gas.

 

sparks

 

I run sparks tt pipes on both my bikes. I went from a Turner Eliminator 98 to a TT and there was a fair amount of power gain.

 

From your sig. it looks like Baldwin did your motor work. What do they recommend? Thats who you should talk to.

 

Sparks is a thing of the past for 250Rs. Cant go wrong with ESR

 

ESR!! Fit and finish are second to none along with performance!

 

Why do you think Sparks is a thing of the past? Is it maybe because their waiting list is months long?? I think ESR makes good stuff, but for my applications, the Sparks TT pipes make the most HP. He was asking about a Pro-X cylinder, and I personally think, that for sand duning, Sparks makes the best pipe. Once you need a BB pipe, I am not so sure.
