This is a 2004 crf150f. I bought a dual exhaust kit from pazoma and it was a nightmare to install. Nothing lined up. I ended up cutting the exhaust into many sections and welding it back together to make it fit. I also installed 2017 crf150f plastics with a crf150r front tire, caliper and front fender. Additionally I added cr80r forks. Ended up looking pretty good.
