I'm sure its a question everybody asks but I'm going nuts trying to make sure I get a good exhaust system. For one heres a link to want I'm interested in http://www.gopartsdirect.com/2005/it...Placeholder=24
Does the white brothers carbon pro II come it doesn't say slip on or require head or mid pipe so is this a complete exhaust system or just the muffler. I'm confused because the fmf offer seperate mid pipes, headers and mufflers white brothers don't. If this this isn't a good system let me know your opinion. I plan on getting the atv pro power pack also

Yeah, White Brothers make a good pipe and it will make some good power on the 660. At $626 it is the whole system. But I am going to buy a CT racing pipe for $543 that comes with titanium needles and jets and when dialed in right it will make 49-50hp at the rear wheels with the correct intake. Personally I like the CT pipes, and I think they make the best power on the 660 when tuned right. However I have heard that they are hard to tune but we shall see.

 

You can get a full LRD Pro4 system from Motosport outlet for around $520. Great system. Best exhaust I've ever run on a quad.

 

I stumbled onto a good deal on a Pro-4 Series full system assuming like yours. I really like the price and the pipe itself looks pretty top notch as LRD is a well-respected company. I would like to know what you think about the top end pull that it gives? I am looking for a little more top end pull on mine in particular. I love the power curve of the CT pipe, but if this one makes similar numbers to the CT then I will probably end up buying one. The CT was dynoed without an airbox lid and a K&N filter and it didnt sign off at higher RPM's like most of the others that I had seen numbers on. It pulled all the way to 9K RPM and jumped 32hp at 8500 RPM. I would like to have something similar to that.

 

To put it bluntly, I was blown away when I started running my LRD system. Even with a bottem end/midrange cam, the pipe still pulls hard in the upper RPMs. I just got off the Raptor at a local motocross track about three hours ago. My quad does run out of power on top eventually, but slight changes in gearing and tire size can limit the loss. Even with 18 inch rears and taller gearing for motocross, my Raptor still pulls on the top end. This pipe makes awesome power all around. It is the best system I have run on a quad as far as quality, finish, customer service, ease of install and performance gains.
