Just put a White Bros E series on my 05 last night have not had a chance to ride yet, E-bay special, repacked it and polished it up and lookslike new, still anxious to see waht it sounds like and if any performance gains. It should put my jetting spot on, I was a little rich before with the stock pipe and K&N, I made jetting changes with the filter earlier.

I'm running a Dr. D Ti. I wouldn't run anything else. I also lowered my radiators. It turns just fine.

I have the FMF 4.1, but just the slip on. But I want to get rid of it and get the Dr.D. When I rode my buddy's 06 with the Dr.D pipe it just felt so smooth.

That's pipe i want to get..

Where did you buy the pipe?

I ordered it from Altus Motosports in OK. Any Parts Unlimited dealer should be able to order the part for you, which is # 1820 0853.

Anyway the power is similar to stock, but on steroids there is more power everywhere. It's lighter then stock too and really an awesome built exhaust.

The only downside to the exhaust is it's not cheap.

Yoshimura RS-2 full ti system. Power is similar to stock, just more everywhere with really good throttle response. Excellent build quality and decent price.

Does anyone have the scoop about Vance and Hines coming out with some dirt pipes now that they've taken over White Bros?
