Hey guys just wondering if you could help me out i have a 2007 yz450f and i was thinking of purchasing a drd or rocket exhaust slip ons i currently have a fmf power bomb header but i hate how the stock exhaust has such a tiny exit hole after all the better she breathes the more more power she produces ;) thanks guys!

I've always had good experiences with Dr.D. Fit, finish and pretty reasonably priced.

I have had DR Ds on both my Yamahas. Latest is on a FX. Great fit and sound (NS-4). That gets my vote

Premium quality, very good performance, moderate price, excellent customer service.  Just a great value.

My Dr.D full system on my 09 runs great but the header now interferes with oil filter replacement and emperor racing skid plate.

I'm a Dr D fan also. Fit and finish top notch - I didn't even have to add any exhaust sealant at the pipe/ silencer junction on either the YZ450F or YZ250F. Better price point than any of the major brands as well.

DRD = high value

Rocket = low value, low price
