I think I actually heard him say that's how he feels about the YZ pipes in a video intervew or something.

Here's a guy who is one of the best test riders around, and he loves the YZ250.
If he builds a pipe, or a complete system and it's anywhere near reasonable pricing, I'll buy one.

They close at 4:30, missed is by 10 mins. Ill call tomorrow

Think i have sample photos of the Dr. D's YZ250 pipe, kept them in my Facebook.

That is my bike #35. You will be very pleased when Doug puts the pipes and silencers into production.

How did you like it? What did you have to compare it to?

I just got off the phone with Drd and they said it was pushed back and will most likely be coming out in two months. Cant wait to get on of his exhaust systems on my 250

Yes I can finally stop waiting for it! this was the pipe I wanted to replace my stocker with.

Dr. D pipe and silencer spreads a nice little power increase through the midrange of the power band. No real increase at low or high RPM's. I have the final test pipe,. it is the production spec. The silencer I have is the first one he made in 2009. Since then he has added a second mounting bracket and the silencer has gotten a little longer. I will see Dr. D at the Dealer News Expo in Indianapolis next weekend. I hope he will have the pipes on display there. There has been several production delays, but I think they are coming soon. I have compared his pipe to Pro Circuit ( good top end increase), FMF( almost a mirror of the stock pipe) and the stock pipe. Dr. D seemed to have the most useable power increase. A nice useable increase in the meat of the power.
If you look on the Dr. D facebook page I have added a couple photo's of my bike with the complete exhaust system. The pipe is quite large compared to stock and other aftermarket pipes. But it is well tucked in and fit was perfect.

Does this mean that the DEP pipe is still better?

Power increase is all throughout the powerband ---- sure one would have known about this had the forum, when it upgraded, didn't lose the dyno graphs that the gentleman Stimps posted at one of the stickies

Happy to dyno one and compare. Will re run a few alongside to make sure fair. Just send me a nice shiny spanking new pipe and silencer one way carriage and will sort it out :-) . Same offer goes for a 295 kit etc etc.

Many of the dyno charts were posted in my garage. I still have them in a sub directory somewhere.

I will send you the HGS pipe when you get the rest of the pipes.

Oh sir, i didn't know it that the bike belongs to you. I just copied the photos that showed Doug Dubach's pipe.

I could have mentioned your name as the source of them pics when i posted it

No send it to me. LOL
I think its awsome if the DRD pipe is a stock black finish.

I am anxious to try one. The dep pipe is great, amazing even, Still, I think theres room for another well designed pipe and silencer.

I'm wondering about that. The market doesn't seem to be able to do a whole lot with a YZ pipe. The stock setup sets a pretty high bar.

But the more I monkey with my YZs the more I realize the amount of fake "hit" that has been tuned in to the bike. Seemingly for the sake of the magazines. They would pan any two stroke that didn't have it back in the day. The "hit" a YZ has isn't a bust of power. It is a strong recovery from a tuned in lag. A lag that can be tuned out.

Imagine the reaction of these same magazines to a four stroke that had "hit". Such a rig would be the butt of many journalistic jokes.

It would interesting to see a sort of de-hit kit come from the aftermarket. A box with some parts and some detailed instructions for an owner to quickly remove the tuned in lag that produces the fake "hit". I would imagine if a company like DRD would create a pipe to work in concert with these simple modifications. A rider could really transform a more or less stock YZ into something very different in one step.

Looking through these threads you see nearly every day some rider considering this or that mod to tune their bike. Other riders will try to sell them on it because it works. Others remain skeptical. Usually the skeptics have never tested the mod.

Remember when the SST pipe came out as a system that required the purchase of both the pipe and the silencer? People knee jerked into buying it because it was different and costly so it HAD to be good. WRONG!

For about the same sort of cost, adjusted for inflation. Some company could put together a comprehensive kit that really would transform your bike in a positive way.

HAHA...oh c'mon, MXA says to just bolt on a PC or FMF pipe and get 2HP. These guys are just drinking the advertisers cool-aid. haha

You know, I hear that from all the local riders around here as well on this site. I am sticking with the stock pipe fro as long as I own my bike for that reason. You can sure find plenty of new stock pipe for sale everywhere and they are cheap so I am all for people buy those nifty aftermarket ones so I have a plentiful supply on fleabay.

DEP outshines the stock pipe, not by leaps and bounds, but enough for me to be happy with mine. If I could of found a cheap stockie at the time I needed one, I would have gone that route.

Don't get me wrong....if I couldn't find a decent stock pipe anywhere and in need of a pipe it would be the DEP enduro pipe. I guess in my case I have an Eric Gorr motor so looking to add more power is an after thought.
