no custom exhaust unless you purchase a decent canister and get it set at a decent height and angle … too many custom exhaust look and sound like shit … that is why you should at least purchase a brand name catback if you have the money 😛 a decent full turbo-back exhaust system should be the first on your list rather than a fmic. Your car will be more responsive, have a more aggressive tone as well as make some more power. FMIC at times is more of a visual mod than a performance mod if it is not well suited to the car and can make a car laggier and also heavier … hahaha choice is yours guy
