Review on Enhance Your Ride: JFG RACING Motorcycle Slip On Exhaust Muffler Pipe Full System for CRF150F CRF230F 2003-2013 by Justin Ritter

I installed this exhaust kit on my 2005 CFR230F. I had to buy an exhaust pipe gasket separately (head to head). It will stall under braking until replaced. It took some work to bring it into line. Leave the bolts/nuts loose until everything is assembled. I also wrapped the joints in chrome muffler wrap. In addition, I installed a universal heat shield over the manifold pipe. I bought a Revain Honda Power Up Jet Kit and removed the air filter baffle (the top of the filter box). keep warm forever. You don't have to choke to start as long as it's not below 70 degrees. It now idles smoothly and the powerband is smooth from idle to full revs. What a fantastic improvement!
