What are the top few exhaust's for the 700R? I was thinkin' about getting a Pro Circuit. Has DirtWheels done a pipe shootout test for the 700R yet?

 

For the most part if you stay with top companies the exhausts are going to perform very close. It comes down to personal preference more than anything IMO. The LTE duels have shown to produce better HP for longer than a full single.

Not to say these are the best but they seem to be what I see on the 700's the most.

I have never rode or heard a quad with HMF. I found some HMF slip ons quite cheap on ebay. HMF slipon with factory headpipe be worth the trouble or would a complete system be much well worth it.

 

I think it is worth the extra for a complete system. A slip-on will give you gains but not much above removing the SA from your stock pipe. If looking for best performance for the money start with a controller, Pro-desing intake/filter, no lid and remove the spark arrestor from stock pipe. This gives a nice increase in power and you van add a full exhaust later.

You can also modify your stock pipe. There is a plate about half way in that restricts air flow you can make more holes in this to increase the performance a little more.
