Ok, i have a new Akrapovic Evo. full system coming in and i'd like to know what other upgrades i need to have this running at full specs. I heard that you'd need a power commander to not run the engine rich, as well as a new filter. Any suggestions to what types to get?:thumbsup:

Ha ha, that would depend on the relationship you have with your shop. it is really easy to do, just pull of a hose and plug it with a bolt and a hose clamp. Most shops where you are just a "casual" customer will give you some "voids warranty" speech and will not do it but you can try.

Here ya go i went ahead and did the leg work for ya :roll: http://www.rogueracing.org/flap.htm

Ah man! thanks a bunch for the 411. I'll go ahead and try to ask, but it seems easy enough to do by myself so.. Thanks again.
