Im looking to upgrade my exhaust, Im not sure what to get though I have heard the pro circuit full system for my kfx-400 would be a good choice.
Any insight ?

 

Hey Man, I have a Pro Circuit (slip-on only) and have no complaints. It was on the quad when I bought it, but I have had some seat time on a couple stockers and there is deffinite difference in torque.

I'm not sure how much difference a full system is over just a slip on...I've heard that the stock EX head pipe is fairly good and they say that there is't a whole lot of increase. But I'm not afraid to admit I have no idea what I'm talking about.

I'd say most any of the systems that are in the same price range (and up) as the Pro Circuit are good.

I love how josh's exhaust sounds

here's a tough one. what if you got an 86 quadsport that they don't barely make **** for. its got some supertrapp pipe on their and sounds mean but its gone to ****. all i can find is universal this and universal that and a dg full exhaust. i hear dg is almost as bad as it gets. whats the deal on that and can i get any performance out of universal ****?

 

hmm not sure on the KFX.. but on my honda I have gone through many differnt exhausts... umm started off with a FMF it was ok.. then moved to all White Brothers stuff they were pretty good... now I have an Alien exhaust on it.. so far the best performance... Curtis Sparks would be even better for it I think and would not be soo dang loud.. That Alien is insanely LOUD...

then on my 450.. I was going to use the Curtis Sparks but have heard that the LRD is better... so I ordered and have a LRD now for it but have not had a chance to put it on yet...

some exhaust may require a lil extra like jetting and changing out filters and stuff just depends I guess... when I get the LRD put on I will also have to get a jet kit and an air filter mod...
