well i got sponsorship applications from Dubach and FMF, not sure which i should go with. the discounts are pretty close so i'm torn. has anyone run both exhausts? which is better?

I run the Dr. D on my YZ250F because (1) Dubach is a supporter of DRN and DirtWeek and gave us all some killer riding tips in the DirtWeek moto schools, (2) Dubach knows Yamaha 4-strokes better than anyone else, (3) you'll get better personalized service from Dubach Racing vs. FMF (or most any other brand), and (4) the Dr. D exhaust is an excellent addition to the 250F power and delivery over the stock system.

I've never tried the FMF, but I believe in supporting those who support us!

I've only heard good things about the Dr. D system.

I have one and love it. It makes great low end but still revs out as good as stock easily.

I've got the Dr. D on my 450 for the same reasons Nikki listed. Great folks with a great product.

I just got the Dr. D with the quiet insert for my YZ250F. I bought it b/c of all the recommendations from others who have bought it.

Now I just have to figure out what jetting changes I'll need to make with the silent insert being used.
