This test was performed at Kevin Gigot's in house dyno. My personal stock bore 2006 yfz. Hoosier tires. 2006 Venom ported stock OEM valves and springs. 187+2.5 Web cams cam modded. Sredrum race carbs bored out stock carb to 41.5mm. FCI intake. Venom 14.1 piston. Stock 06 crank.

All out power, no db limits required. Also some pipes were cut down to make them "shorties"... IE Sparks, Jardine M4, Rossier. You can not buy them as short cans. You have to cut them yourself. Also as of Feb 09 the Jardine RT4 is no longer made. The Jardine RT5 is it's replacement. The Nmotion pipes are no longer made. However JSR is now making the old Nmotion pipes and so you can apply everything from the Nmotion pipes to the newer JSR pipes. M4 is not making the Nmotion copy pipes any more either. They make pipes however, but not the same pipe that was tested in this test.
