Dr. D - Stainless Steel Exhaust System with Spark Arrested Aluminum Silencer
This exhaust works very well, my bike has jetting and air box/filter mods. And the system works out perfectly, better power through out the power band, and a little more down low. It was a little too loud so I had to install the cone and really didn’t hurt performance at all. And looks great as well.

Dr. D Stainless Exhaust System
I installed this exhaust on my Crf 450x. Installing the exhaust was a better fit then the stock exhaust. The power and mid range is way more then stock. The sound is a little louder than stock, but DRD sells a quiet core if you think it’s too loud. My bike did require some jetting. Dubach development hands down is the way to go, and best bang for the buck for a top quality complete exhaust system.
DRD Rocks!
