13-14 HONDA CRF450R: DR.D NS-4 Titanium Slip-On Exhaust With Titanium Can

Complete Systems

Every DR.D exhaust is built, developed, and tested by Doug Dubach.
DR.D pours more time into track testing, with more experience, than any other company.
DR.D exhausts are not mass produced, each exhaust is unique and each has been developed on the track to best improve the bike's power character.
You won't find 'universal' components, such as heavy springs and gaskets, in their construction because cutting corners, on the track or in production, is never beneficial.
Take it from the man who has spent more testing time on a Honda, Suzuki, KTM, Kawasaki, and Yamaha than all others combined.

If it passes Dubach's test, it will pass yours.Performance improvements over stock system.Features titanium mid pipe and titanium can.Lightweight magnesium end cap; riveted on for increased durability.Welded construction for reduced weight.Removable bolts at inlet cap for easy repacking.Includes roll style packing; extends packing life.All Titanium / Titanium systems come with a U.S.F.S.-approved spark arrestor screen.For the racer that requires ultra-lightweight and performance, the DR.D Ti / Ti (Titanium Tubing / Titanium Can) is your exhaust. Receiving more magazine 'shoot-out' awards than any other exhaust, the DR.D Ti / Ti features a titanium mid pipe and muffler. Uniquely track tested to improve hit, delivery, and pulling power with substantial performance gains while drastically reducing weight over the stock system, the Ti / Ti has no equal. Built and tested for superiority in strength, welded construction (no springs), magnesium end cap, removable bolts (not rivets) at the inlet cap for easy repacking, and stepped perforated core (reduced heat) for increased durability set DR.D apart in construction, and on the track.
