Hopefully this allows, if not delete it..

Below is a condensed version of the pipe shootouts for those looking to see all the information laid out.

Thanks to:

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.

Ok thanks for your efforts, but....

You have no build info provided. These are two different dynos. Way different motor builds... one highly modded and the other cam mod and filter...

So now I have to edit the post with the needed info to make it accurate.

Well that was the issue I had with the two posts, trying to figure out what was what amongst the 2 threads and 30 or so pages. Thought it would be easier to put all the info on one post if that makes sense?

Yep makes sense. No worries.

I edited your post with the added/ corrected info. Let me know if it makes sense?

In the un limited pipe test (1st test) we members here on central and yfztech voted on which pipes to test, and which pipes we could test. As in 90% of the test pipes are members personal pipes that they chose to send to me at their expense. So if I pipe was not tested it was either 1: not sent in or 2: no need to test a common pipe that ALL the mag dyno any ways..... like HMF.

Mostly because if it wasn't sent in, it didn't get tested. Period. Besides people can say all they want or bash Dirt Wheels, but between Dirt Wheels and ATV Rider they cover alot of dyno pipe tests, and there is no need to dyno what has been dyno'd already.
