I installed a set of dmc dual afterburner exhuast. Its the full system. Runs great, only pops every now and again on decel. I really would rather put the money towards pro armor doors but dont want the engine life to be cut short due to running lean. How do i tell if i need one? I have the stock air box, doesnt seem to get very dirty at all like some peoples i have seen. I will eventually end up with a vent racing box or ump, but for right now everything is stock minus the duals. Also, On a night ride the other night the headers were glowing pretty good. Any help would be appreciated. Thanks.
