I'd be stunned to find evidence of "more restriction" in the gemini, so please back up you claim with fact. The exhausts follow identical bends and use the same muffler in their current iterations, ever since berk made the most recent change to their exhaust.
Most dynos show ~6-7 PP gains for FI, berk shows 3-5, as does invidia.
