  • The DR. D complete exhaust system is birthed from Doug Dubach, who brings years of experience to the motocross and supercross scene.
  • DR. D constructed this complete exhaust system with an aluminum muffler in conjunction with a magnesium end cap to reduce weight and stainless steel head and mid pipe to provide long lasting durability.
  • DR. D welds the stainless steel mid pipe to the aluminum muffler to eliminate weak points and excessive weight in the exhaust system that spring connections can cause.
  • To create a solid mounting point DR. D uses a CNC billet hanger on the extruded aluminum muffler sleeve.
  • The magnesium end cap on the DR. D complete exhaust system is easily removable to access the spark arrestor screen. With the spark arrestor installed the exhaust system meets USFS approval.
  • Repacking the DR. D aluminum muffler is simple with the removable bolts on the lower end of the sleeve.
  • The DR. D complete exhaust system includes: aluminum muffler with stainless steel mid pipe, stainless steel head pipe, USFS approved spark arrestor.

The best bang for your buck!!!
" I put this exhaust system on my 09 YZ450F, and it felt like my bike woke up from the dead. Not only does this system look cool and sound good, but it also made the throttle response more snappy. I will highly recomend this system to all of my friends! "

Great Exhaust
" After running another brand complete exhaust for a couple years i decided to make the switch to the Dr.D I couldnt pass up the 50% off at motosport. I noticed gaines from bottom mid and top. Very noticeable compared to the other brand. It seemed snappier and had more rev on top. Definitely recommend Dr.D!! "

pro circuit
" i bought this pipe about 2 weeks ago, i put 10 hours on it, and it was already blowing packing like it was confetti. before this pipe i had a pro circuit slip on t4 and that slip on made more power then this full exhaust. looks wise i like this pipe but to change the oil filter on 06-09 yamaha yz450's you have to loosen the header bolts because is has such a low bend, i would recommend pro circuit over this pipe any day, but for a full exhaust 500 bucks is not to bad "

Nice system
" This is a nice less expensive alternative to the costly twin pipes on the crf250r. The only problem I had was with installation. The center bolt boss did not line up with the hole in the subframe. Was off 1/16th of an inch. I had to slot the silencer bracket a little more to make it work. "

" I bought this pipe for my 07' CRF450R in anticipation that it would smooth the power like the Dr D of past. WOW was I wrong, hold on to your panties, mid to top was out of this world, not what I was looking for but not a negative. I give this pipe bad marks in the Durability category, the rear mount broke, which is common but I never let the bolts get loose and there was less than 15 hours on this pipe. That being said, I am not much past Junior local level and nowhere near hard core. If just the mount broke I would be okay with it but the entire core was ruined, I'll replace it with a disposable FMF. "

Great Value
" This pipe really wakes up our yz250f's. We are so impressed with them that I just ordered on for the 450f and am sure that we won't be dissapointed. Only down side is that they are a little louder than fmf or pro circut if that is a concern for you. "

Great power!
" This pipe is definitely worth the buy. With the stock exhaust on my rmz250 i could hammer the throttle in second without lifting up the front end. With this pipe, it brought the front end up about 6 in. I still have to get the carb. rejetted and i can't wait to feel the power afterwards!! "

Amazing price for a great pipe
" This pipe really brought my YZ 250F to life. It adds all around great power. It sounds great, and it revs much faster. The best thing overall it the price. "
DR. D stainless exhaust.
Asked by uxcryno, Orlando, FL
You are correct. DR.D offers their pipes two ways, with or without spark arrestor. You can not spark arrest a non-spark arrestor exhaust. But you can remove the spark arrestor if you like and it would function just like the race pipe.

What jetting changes will I have to make with the Dr.D exhaust on my 2008 YZ450F?
Asked by tr4186
You may want to contact your local service department tech for jetting specs. This can vary dependent on variables that are very difficult to convey. Some people say that you don't need to jet and for some that may be true. But if you want to benefit the most performance than I would suggest getting the jetting done to specs. But that I can't help you with.

Asked by blmx160
You might want to reference your service manual to see what is required switching out the exhaust.

if your bike is efi it should do it on its own, thats the advantage on efi, not having to mess with jets, although u have a suzuki so u probably will!!!!
