I am looking at new exhaust for my KFX700. Considering MUZZY, White Brothers, HMF. Does anyone know about Penland's dual system? I saw a comment that said: "This is the top of the line performance pipe for the KFX 700".
Prior to this I had not heard anything. Any feedback is appreciated!

 

Any of those pics that you listed are good pipes.

Personally, I would go with the Muzzy. It will give you the best gain on a "stock" motor. Meaning no high comp pistons, head work, cams, etc.

The tone of it is awesome, I don't think any other pipe can match it's sound.

It gives good lowend power, which is great for trails.

As for the other pipes, I know that the White Brother carbon pro is comparable to the Muzzy. It may make a little more power but it is also louder and there is no quiet core or spark arrestor available for it but you can get the quiet core and spark arrestor for the Muzzy which is nice if you have to meet certain DB limits.

Check out my picture page to see my Muzzy system on my V.

The only complaint I really have about it is the fact that you can't ride in shorts, doesn't bother me as I never do anyways.

 

How about the DMC Alien Dual Setup?? I have a friend with it, and besides being extremely loud its an awsome setup and you can definetly feel the difference.

 

No, don't even consider the DMC Dual System.

That is what I had on my V before my Muzzy.

The DMC was an obnoxious loud, kind of like a Harley that is loud as hell.

I also got more power gains out of my Muzzy compared to the DMC, you could feel a big difference on bottom end and midrange.

 

Hey whats up if i were you i would get the Muzzy
