What slip on produces most power!!!!

[yellow400]

what slip on will produce more power for my 400ex. I dont' really want to rejet. but i will get a k&n air filter with it. Thanks

If you put a Filter and Pipe on you will need to Re-Jet. I think the TC Pipe is one of, if not the best slip-on you can Buy. It is a Racing Pipe.

Depends on where ya live. My recommendation is a White Bros. E-series pro-meg.Its fairly quiet,puts out great power gains,works good with a filter when re-jetted.And, you can adjust when you want your power to"kick" in, with adjustable discs.

i heard pro circut are good but they are loud :eek:

White Bros E-Series or a TC is prob the best

dirt wheels dyno tests in 2001 march mag. said that the TC and the e series slip ons made the most hp.

i have a stroker slip-on its makes good power all the way through the power band also has a nice rumble too it.not too loud but much better than stock also about 1/2 the wieght as stock pipe.

i just got my pro circuit t-4 2 weeks ago and,WOW what a difference. id go with a t-4 they boost yur power all the way around, i ride everything(mud sand mx dunes) and it made a difference. the only draw back is that it is loud as balls:D :blah
