Racing twins for D7 - Info Needed Please

[Racer220]

Heard there were racing twin pipes built for the D7, but never got any info on them. Unfortunately I could only make one race this year so I kind of to a back seat to prepping a race sled. Looking at devoting the whole season to racing next year and want to get a little input on how they were working. Any other hillclimbers upgrading or just trying to get rid of a set? Is there porting or any other mods associated with running them? Any info would be greatly appreciated. I'm still just running Semi-Pro Improved/Mod.

Thanks

I am running the slp race pipes on my 07' d7, and they work great, I also have porting, shaved head, reeds, and a Fastrax fuel box. I ran 8500-8700rpm at Jackson this year. If I go turbo next year, I will sell them. Fastrax Motorsports did the porting.
