I just installed a KLX300 pipe and headder on my 18". I also installed the O2 sensor bypass that I got off of ebay. I got some backfiring on deceleration for the first couple runs down my street. Seemed to work itself out though. Maybe the ECU adjusting the the O2 sensor being bypassed?
Didn't notice much difference between the two pipes. 300 is louder, maybe a bit better throttle response. They weighed about the same with the 300 being slightly lighter. Time will tell.

Guys I found this - Kawasaki KLX250S FI MAGNUM EVO-Tech Motorcycle Performance Chip
The company- Magnum - is irrefutably reputable. This kit ties in to the O2 sensor. So it is likely that "closed loop" operation is still a working function of the EFI system. If so, this is quite sophisticated. Closed loop ops allow great fuel economy for cruising and during lower performance riding..

I just spoke with my dealership and they recommend a Yoshi slip on. He said that I can install it then bring it back up to them and they will tweek the FI mapping. He said, it doesnt really NEED any changes but they can make some changes that would be beneficial. Im probably going to take them up on that.
