I have one and I have ridden quads with the sparks full, fmf full and the yosh slip on and I liked the DRD the best of all of them. I was especially impressed with the low to mid gains. Dirt wheels just did a shootout of about 10 slip ons and they chose the DRD. On their dyno is showed 47.1 hp with the lid off and jetted. PM me if you want one, I can get you a good deal on one.

They probably the best pipe, i mean they make some killer pipes for the CRF, YZ450F, YZ250F, so i mean this is another big bore 4-stroke yamaha quad so they probably got the secret right on this one....

Quiet and powerful is definitely the wave of the future. As soon as everyone realizes that, the image of ATVs will be much better off.

I like the Dr. D!!!!!!!!

I got plenty of holeshots like this one as soon as I bolted it on!!!!
Its not real loud... The only problem I have had is one broken bot I had to drill out, but that was kinda my own fault for messy with it too much.

The "Dutchman" where this shot was taken is a fast MX style HArescramble race. Over 4 miles of MX track......

My point: the Dr.D has great low end torque and grunt yet it really opens up in the top of the RPM range when need be!!!!!!!

Dubach really knows his Yammi's

my gytr has fallen apart and am looking for another pipe. dubach looks good from DW but they also said that CT was a good pipe. my friend put a CT on his DS650 and it became slower!! (rejetted many times looking for that missing power.) so i will be skeptical until i see a dubach in action. FMF impresses me, Yoshimura impresses me, but cost is an issue. cost of a dubach?
