Was pricing out a new KFX/Z 400 among the local dealers. I requested the price-out for the bike, pro flow kit, and a complete Pro Circuit Exhaust system (headers and can) based off the recent dirtwheels issue on the pipe shootout. Two dealers steered me to the Yoshi complete set saying that is the one their parts/maintenance people say work the best as far as power for the z400...two dealers referenced this. Does anyone have either of the two on their quads and can provide me any type of feedback on them...recommends on one over the other...experience with them both...where the biggest power hit is...any input would be appreciated...thanks

It looks like i will be going with the KFX... dealers repeatedly offered them cheaper...here is an outlay of the pricing:

1) white z400, yoshi complete set, Pro Flow kit, Tax (Utah) and L, for $6350
2) KFX, Yoshi Complete Set, K&N fitler w/ Jets, Tax (Utah) and Lic, for 6175.00 - this is the one I am going to get...same quad as the z400 so i will take it for $175 less and actually like the Kawi green the best...white looks wicked too though.

New to your community and looking forward to exchanging information and tips...well probably be receiving tips alot more then giving
