I just installed the ARCS GP3 Stubby exhaust by Austin Racing. V2 Black can. Looks gorgeous. LOVE IT. Sounds great and fits perfectly. Only problem. I noticed my idle is kinda rough. Jumping +/- 500rpms. I am ordering a PCV and BMC next month. Think this will smooth it out. the other problem may be this crap @$$ gas the Army sells us. Is that a possibility? Thanks.
