What is the best Full Exhaust System for my 2002 crf450r? thanks!!!
The type of exhaust you want is the white brothers XCR exhaust. Its found on CRF450R's that are used for track days. It will give you a good boost of power. I saw one but it was listed as being for the 06/07 model so i would do a quick check to make sure it fits ok. I found a link to a website that you can buy them off.
