Which pipe should I choose?

[iaboy30]

Im looking at getting either the White Brothers E-series slip-on or the Pro Circuit T-4 slip on for my 400ex. Which one is the better of the 2?

next time do a search but outta those two they are pretty even i would have to say,but i would go with the white brothers.....if you plan on buyin a slip on look at HMF....very good pipes from what i hear

Go with the white bros....they are pretty nice

Never rode a T-4 but i have heard good things

I have ridden an HMF equipped 400ex and it was awesome. I think they have a really quality pipe. I have a WB eseries on my quad and i love it, it sounds really nice and it added power.. id go with that. I hear alot of good about the T-4 also. I i think no matter what you get, your gonna be good. If noise is an issues.. def the WB.

I have the White Bros. E-series slip on and I like it. I run it with 12 discs. it sounds good and performs well. My buddy has the pro-meg and It is sweet. maybe a little more power from it.

CT Racing's slip on one the dirtwheels pipe shoot out for the 400ex. Go to CTracing.com I have one of their pipes on my 89 250r and it is awesome.

Go with CT or sparks. They will both make more power than the T4 or E series. The e series is real close though.
