Drd exhaust or rocket exaust

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

Thanks guys had one on my 04 there pretty good just was wondering if anyone like running anything else



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
