Ducan Racing Double Barrel

[400MXer]

I know that my pipe is going to get ripped apart because everyone likes the Curtis sparks (I have nothing against sparks) But have any of you ridden a quad with a duncan, or rode with a person with a quad with a duncan..lol. What do you think....How would you compare it to other pipes. I've ridden with a sparks but that quad had a million dollar motor. the only other pipes i've ridden with was FMF, Big Gun, DG, and some of those. How does it compare to the TC, or a stock 400 with Sparks?

I had a big gun and a duncan double on my 400ex at different times, but I would have to say Ilike my duncan. it look neat, sounded good, and Ithought it performed well. heres the ratings on some pipes from atv sport. sparks- 27.8 hp duncan- 27.3 white bros e-series- 27.6 and those were really the best of the performing pipes, there isn't too much difference between the 3. just my input.
