The 2013 CRF450R is a great bike in most areas, but the engine department needs help along with the extra weight the dual exhaust carries. The DR.D system does just that, it trims nearly 3 full pounds off as it is the lightest exhaust system on the market at 7.9pds in stainless steel/carbon fiber. Our Titanium? It is even lighter. The performance increase will be slightly better off the bottom, carrying into a strong mid and continuing to pull farther than the stock unit on top.
Motocross Action Magazine held a dual pipe shootout on the 2013 CRF450 that featured in the March 2013 issue. The DR.D dual was the quietest exhaust (meeting sound regulations) and also the lightest exhaust. The system was a Stainless Steel/Carbon version. DR.D was the only company not to use a titanium head pipe/ mid pipe (which we do offer) and still reduced the most weight when compared to a stock system.
