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.

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!!

Great Buy

i purchased this exhaust last year for my '09 crf 250r and it def woke up the ole girl! this pipe hits hard low and carries through the top! plus sounds amazing! the only thing is the head pipe is kinda weak mine was dimpled a quarter inch from a little rock kicked up from my friends bike, other than that i would def but this system again!

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.

Will the DR.D just bolt on and run on my sons xr100, or will I need to do extra mechanical works?
Can I run the BBR120 bore kit with this exhaust without to much hassle.

Yes, the Dr. D Complete Exhaust With Spark Arrestor would work great with the BBR120 big bore kit and will bolt on with no modification to your 2002 Honda XR100.

Jetting?
I have fitted to WR250F, 2010 and it is bogging down when I snap the throttle back. Please could you advise. Is jetting a solution and if so, could you advise the settings. Thanks Pete

It sounds like you do need to re-jet your bike to correct that low end bog. More than likely you will need to change the pilot jet and possibly the main as well. I can't really recommend specific settings as it would depend on how your bike is jetted now as well as your location (altitude/temperature). I would recommend looking at the JD Jet Kit for your bike as it would come with instructions and recommendations to help you tune your carburetor perfectly.

Will DRD mate with megabomb header (wr250r)?

This DR. D muffler will really only work with the DR. D headpipe that it comes with. If you already have the FMF megabomb Head pipe on your bike I would recommend looking at the FMF slip on exhaust systems as they would fit up perfectly with that head pipe.

Jetting?

Unfortunately I can not recommend any jetting specs since there are too many variables that come into play. The best thing to do is install pipe and then check your plug. That will let you know what you should do with your jetting. Worst case scenario, contact a local shop for recommendations.

drd is one of the best pipes you can get for your yzf it helps alot with your low to mid range, fmf isn't bad either but if you get fmf you just about have to get the powerbomb header plus it just about only helps with your mid range to top end, hope this helped

How many do I need...?
I have a 2008 Honda CRF250R (which has dual pipes) so do I need to buy 2 kits or do I just buy one and plug the other one? I assume I need two but I read one of the other reviews where a guy went from 2 to 1 but I think it was on a yamaha. I'm new to the sport so I know this probably sounds like a silly question.

Unfortunately DR.D only offer single exhaust systems for your Honda. Basically you will convert your duals into a single pipe with this system. If you're looking for dual exhaust, take a look a the Pro Circuit Exhaust Systems, they offer them in duals.

Hp?
which pipe would have more power gains the DR.D system or the FMF 4.1 with the megabomb?

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!!!!
