ok i hit enter on accident, but i own an 04 KFX 700 and iam thinking of replaceing the stock Pipes, iam not sure what to replace them with, alot of my rideing is threw dence woods and mud, i live in Upstate New York. ive also herd that if u change the stock exhaust that you should re jet the carb and get a new spring, is this necessary?

 

Well you should change the spring no matter what. It takes 10-15 mins and is probably the easiest cheapest mod you can do for some instant jam. I had duals on mine (MBRP) and switched to a 2 into 1 from Muzzy. I like the Muzzy, it sounds incredible and adds more bottom to mid than the duals did. The MBRP is under-rated as far as top end goes.
