Bill- Pipe comparison

Come on Bill, give us the stock YZ pipe vs. E-series test. I'm dying to know, man.

Also, if anyone has any comments regarding the DSP full (not tapered) system, please insert comment here :)

Sorry I have not. I just started a new job and work 12 hours everyday. Hope to get out soon and then we can compare notes.



99 WR400f, YZ timed, MX-Tech suspension, Scotts steering damper, White Bros E-Series (12 discs), tapered header and a/f. Kouba T-handle for the fuel screw. Works Connection billet throttle tube and frame guards. Cycra Pro-Bend, triple clamp mount handguards. Thumper Racing rad guards, Renthal Jimmy Button highs, YZ Tank and IMS seat, YZ number plate, odo removed, EKP #4, 50PJ, 175MJ at 500-1000' Thanks James Dean!


Have you tried your experimentation yet? I just bought a used E-series Promeg Shorty (alum), when I install I'll post some feedback on it vs. the stock YZ pipe
