2011 yz450f exhaust recommendations ?

So I'm looking around for pipes but just dont know if they're all the same or do others make a bigger difference than others. Or or if i should stick to stock pipe and should just buy the gytr programer I heard it's the same as changing pipes. Also I'm more of a desert rider than a track rider and advice would help.

YOSH and the tuner :thumbsup:

ARROW and the tuner ! :thumbsup:

Depends on what kind of power you want. Pull longer on top? Mellower and broader or more hit? Spark arrestor required? MXA did a test and preffered the Yoshimura RS-4 and Pro-circuit pipes but that is mx. I have the Yosh and love it and yes the tuner does make a difference. You might try to find some tests and see what suits your needs.

Ordered an MRD last weekend, won't know how good it is for a few more weeks, but at least I know it will be built well. performance should do what the others do as well.

Yosh, is all that needs to be said...

Would the slip yosh work or should I get the full system

I bought a power commander five long before I bought a pipe and found a noticable difference in top end power after the install. Leaning out the fuel map and making it more precise is a great mod just like adding a pipe.

I bought an FMF 4.1 slip on later on and again noticed a much larger gain in mid-top end power.

It's been proven that the stock header flows very well, and a slip on will net the best gain for the price. If you want to save some weight then grab the full setup.

My .02 cents.

From what I have read, almost all of the slip on's are great buys!.

I wish that Yoshimura would make that duel outlet slip on for the yammy though!

I would go for the full system, I got mine for under $475 (Stainless new on E bay)

I did the slip on first, then the full system and i could not tell the difference between the two...the slip on is cool also because it came with the removable spark arrestor...

Thanks for sharing - you just saved me some cash...

What did you feel when you put the slip-on on?

Smooth power with a little more bottom mid and top, also i added two teeth to the rear and removed the spark arrestor...i only ride tracks so it’s unnecessary..

Looked like they clearly liked the yosh the best. I was considering a yosh but went with the MRD instead although I don't have a nice shootout report to tell me it is best, I hope it is comparable to the yosh.

B/c I don't have a subscription I can't read the whole article. I was able to read about 4 exhaust but the one I wanted to read about I couldn't which was the Vance and Hines

Mellowest power down low, more overrev. Everybody but Novices wanted more everywhere. Quietest exhaust in test.

Recomendations were Yosh or Akra.

If you someone was going to buy it for you which one would you choose Yosh or Akra and would you need a PCIII or V

How about not making the assumption that we all know what you mean by "PCIII"?
