Anyone have one of these pipes on their 400 yet? How does it perform? Noise? Durability? Fit? Is the headpipe big? Contemplating buying one> Brent

 

ID GO WITH THE YOSH OR THE NEW DMC ALIEN.....YOU KNOW THE YOSH MAKES HP AND THE DMC IS CLOSE BEHIND ...

 

I got a slip on R4. Looks good. Fits good. Very throaty sound. Now that I have motor mods I may need a full exhaust system and the slip on will not fit the pro-meg head pipe. WB Bros makes a full Pro-meg R series exhaust system. If you plan on motor mods get the full system. I wish I would have. I've been hearing some very good things about the Sparks X-6 and DMC.

 

I have the big gun on my 400ex and the finish is going to crap good setup thougt
but on my raptor I usaed the r4 its much better and it is stainless steel look better longer
