Thinking about ordering a full exhaust system for my 2011 YZ450, I just wanted to get some opinions from you guys on what is the best product. I don't have any motor work done to the bike(not head work or high comp piston, etc). Also price is not really an issue. Things I am considering when buying an exhaust system.

1. Weight of the Ti exhaust system
2. Durability
3. Hp and Tq gains

I am considering these systems currently but feel free to recommend any systems that may fit what I am looking for.

1. Pro Circuit
2. Akrapovic
3. FMF

I'm waiting for my Rocket Exhaust to show up for my Yamaha.

If money is not any issue, I think all the ti units are excellent choices!, Check with motocross action, I think they had a pipe shootout with the 11 yzf 450 and the best pipe was the yosh rs-4. But all the pipes for that bike are really good.The akropovic unit is a thing of beauty though.

I have had Pro Circuit and FMF and my opinion of those two systems are not good. Sub par quality on both of these systems. I have had two Leo Vince systems and cant say enough about them, superior quality of construction and durability. I put about 50 hrs on the pipe pulled the muffler apart to discover that it wasnt even close to needing to be re packed.

Another vote for the yosh RS4. Great system, good power, and best looking.

Sounds good guys, keep the opinions coming, interested in what all you guys have to say. Right now I'm think I'm leaning toward the Yosh or the Akrapovic systems, but I am still listening to all opinions.

Dr. D knows that bike and that exhaust is really easy to maintain and also a good around pipe for that bike cant really go wrong with the dr.
