Actually, the SRT-4 does come with a BOV from the factory. However, it is nowhere near the same design as most of the popular aftermarket ones. Instead, it uses the classic 80's Mopar diaphragm style, which saves room, money, and gets the job done. The SRT-4 doesn't have a muffler or resonator, only a few S-bends to the duals in the back. Trust me, we hear ALL of the turbo noise. We've already taken the lid off and Super-sized the air filter. We've installed the solid motor mount inserts too. We're looking at short shifters next, so do you have any ideas other than the Mopar one RyeLou?
