I have a 2007 arctic cat 650 H1 and i was wondering what i could add on to it to make it perform better. exhaust? chip? etc

 

the typical setup...better exhaust, better air filter, rejet the carb....will be about all that you can do without spending big money. You can look for a spark-enhancer but a chip won't do much since the 650 is not fuel-injected

 

A clutch kit will help out your performance. They wont make any more horse power for you but it will take what you have now and make it work better and get more performance to the ground. Check out EPI Clutch kits they make different ones for your machine depending on the tire size and type of riding you are doing. www.epiperformance.com
