I don't have the fatboy, but i do have the double barrel...and it does pull. really improves lowend, while increasing topend as well. I origionally had a 14t frt. sprocket on and i had to change it because i couldn't keep my fround end down......or it would spin outta control.

From what i hear, the fatboy gives more power yet. Duncan really test's their products.....and you will definitly be happy with the quality.

Yes Duncan does have a web site. It is duncanracing.com. I just got a new double barrel pipe today. I was wondering if you guys know if they make a spark arrestor for it? I was checking out the DMC site, and they have a SA, and it looks like it might work.. Any ideas????

When did you get your double barrel? I heard they stopped making them in favor of the Fatboy4.

I got my double barrel at the begining of last season...since the, they have switched to the fatboy.

Duncan does have a site but right now it is down.

Duncan also makes a spark arrestor. It's $50.

you should call duncan and get a catalog. It's really a great catalog, with just about everything you could want for a quad.

their number is (619)258-6306, and tell them that ADAM PURSER sent you.

Also, if you ever have any problems with your products, with instalation, or tunning your bike, just call them and you will be able to talk to one of thier mechanics for full tech support.

I just got my DR double off ebay, in great shape for a steal at $170.00. DR has stopped ordering their pipes from DMC, who made the Double Barrel, and gone in house. The DMC is the same pipe, with a different end cap.

HOLD ON, WAIT ON SECOND!

I think the Double Barrel Came out before the DMC,Actually I am sure they did. I remember seeing the Duncan Double Barrel Months before any DMC pipe cam out. and also Duncan Makes a DS650 pipe,but why don't DMC?HUH?

Also those Pipes ain't got nothing on my Power Bong P.V.C Pipes, with Coffee Can Silencer. And my Bong Water INjectors add alot of HP!! I got 20Bike Lenghts just by adding the Bong Water Injectors from Reefer Racing. They are Pimp!
