BEAST!!!

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.

Is this the SS/AL SLIP-ON NS-4 pipe it looks different in the pic. If not is there much difference between the two?
MotoSport Staff
Over 9 months ago Location: Portland, OR, USA
Yes this would be the SS/AL slip on for your YFZ450. The picture shown is a generic picture and the may not depict the actual exhaust for your ATV, but it will be of the same style. DR.D only manufactures this exhaust for your YFZ in SS/AL construction.
