Anyone try Gnarly or Platinum II on RM250?

[Crash 142]

Does anyone have any experience with either of these two pipes on a newer model RM 250. I have a 2004 and am looking at ways to smooth the power delivery for MX and get less wheelspin. I'm trying other methods, too, but am just looking for feedback on 'off road' pipes to smooth the power.

Thanks for any help.

I know my 03 has a lot of compression stock, and these RMs were thirsty for race gas. I refuse for race gas to be an option for me. I HAVE a Gnarly that I removed because it ups the compression even more (MUST have race gas). The stock pipe is good, I used fine tuning, flywheel weight and Yamaha's reed spacer to make power delivery more predictable. 1 or 2 less teeth out back helps too.

i have a gnarly pipe for my bike and it works great, it smooths out the hit but it seems like it just has all around more power, i have the grnaly desert pipe, not the gnarly woods pipe.
