Hi, I recently acquired a 1997 Grand Marquis (30k mi.) and am very happy with it (previously only owned Caprices) and it's performance is awsome! Anyway, it has a single exit exhaust system on it and I was looking under there and seems like it would be pretty easy to get a dual exhaust off a simular year Crown Vic LX (maybe from a boneyard?) and install it on my Marquis. From what I've read this conversion would be worth 20 more horses. If anyone has done this, or have any advise on this, pros or cons, I would appriciate any help anyone could give. Thanks!
