You're running a e316G, plan to tune with link, 880 injectors, and a FMIC, but are going to stay with 2.5" piping? That's restricting as hell, and plain retarded if you ask me. Throw your plans in the garbage if you want to keep the performance level up as far as possible, because that 2.5 is restricting, whether you put "dual tips" on it or not. If you think it looks "cool", then go ahead with your plans, but a regular 3" turbo-back (at LEAST catback) will be a much bigger upgrade and allow for much more exhaust flow.
