New DR.D exhaust on my 08...holy s*$%

10 posts in this topic

Yes, I read all the posts about how the 08 is corked up and it needs a pipe to open it up. Well, I waited a couple of months and finally got a DRD stainless full system. First ride....holy sh*#! It looks like the same bike, but it acts like its on steriods. I've never experienced a power gain like this; I feel like I have to re-learn to ride this beast. All I can say is... unbelievable; if you haven't upgraded from your stocker yet, you're missing out.:thumbsup:

I just put my Dr. D pipe's on my 06 YZ250F and my '06 YZ450F. Big power gains on both across the board. Very strong gains in the bottom to mid on both bikes.

I haven't even re-jetted yet....and not sure I can handle more on the 450F anyways.

Great products, excellent look, fit, finish and they produce what they are supposed to .......POWER!

From BTO sports online the pipe was 439.00 for full system. Includes free 2day shipping. Stock jetting seems to be ok at my elevation - 500'. You wont be disappointed. Clean your air filter! Leaving it dirty means more valve adjustments in the future.

Similar prices are available from the TT store, too.

As to the performance gains, I hate to say, "I told you so", ....

No, that's not true. I really enjoy it. :thumbsup:

It really is amazing how friggin bad the stock 08 exhaust is. I mean, it is almost like they wanted to make the bike beginner tame. I agree with the others, I've never seen that much improvement with a pipe on any bike I've ever owned, 2 stroke or 4. I've been racing with a Two Bros Titanium system on my 08, and it runs neck and neck with modded Hondas, no problem on the holeshots.

How much do you need to change the jetting to make it work.

Greg

In colorado with the Dr D we have found a 42 pilot and 155 main is pretty darn good. i also changed my needle up a clip and my 08 rips. My friend has a Dr D and I have a yosh (same bikes) and same jetting on both
