Looking in to getting a 2-1 exhaust for the DX. My short list is the CRF and the Rinehart. I've been reading posts on fuelers for two days and still haven't figured out which would be best for my needs. I don't have access to a laptop so that probably makes my options shorter. I plan on leaving the airbox alone except for the SE air filter thats already in there. Hopefully I can find fuel managment that is simple to install and doesn't cost more than the exhaust did. lol. All suggestions are welcome.
