Description Item #

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.

DR.D muffler

Amazing sound!!!! it is loud but it is not obnoxiously loud. i believe it sounds much better than any other exhausts for 2006 yfz450. i have not had a chance to actually get out and ride with it yet but am looking forward to it. i love this muffler, plus it looks awesome

This pipe rips on my 08 yfz 450. It has an awsome low roar. You can hear it a mile away. It gives you alot of juice when you crack the throtle compared to my buddies FMF pipe.I love it!!

Dr. D slip on

After first day of riding fibers from the muffler packing were exposed in the front and rear of the muffler. The muffler decal was discolored undoubtedly from heat but the muffler itself remains original aluminum color. Emailed Dr. D Tech and Sales with no response from either department. Of course, the slip on provides good power increase over the stock Kawasaki KFX450 muffler. It's never a good sign of a reputable company when they don't respond to a customer's concerns after one day of use. The only Kawasaki upgrades are to the air filter, Procomm ECU set to richest setting, and slip on muffler. This was not a case of running too lean but poor muffler packing and end seals. I want to add the head pipe but will there be a defect in the quality of their pipes also? Now I have to repack a brand new $300 muffler and attempt to improve a defective seal all because the company's quality control is significantly lacking. Truely disappointing.

Drd exhaust

I have an 05 yfz 450 with an 07 crank and a ported and polished head, I recieved my new drd slip-on a couple of days ago. As soon as I pulled it out of the box I said (wow!). This thing looks great and it is built very well. The fit and ease of installation was great, it bolted right up. There were also new bolts and spacers supplied with the exhaust. It looks great on the bike, and has that deep throaty sound everyone is looking for but, not too loud. I have not rode the bike with this exhaust yet (due to the great weather we've been having) but, when I do I will write another review. So as of now I would reccomend this exhaust to anyone... Great work DRD.
