Bought the Dr. D for my son and he loves how his bike now performs for him. Great product
Great exhaust system for trails or track riding. And it looks really good in person too. Great horsepower!
Pipe fit perfect and sounds great.
i have this on my 07 kx250f with an athena big bore kit. definitely give it an awesome sound and has great throttle response too
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!
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!!
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!
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
