I have been looking into a new exhaust system for the 99xj. I have been looking at 3 more often then others... Borla, Banks Power, and Magnaflow... anyone have any insight? I am looking for the full system, minus the exhaust manifold. If its a double pipe that would be awesome but not one of my selling points... I have been favoring the Banks Power Monster single exhaust system, but that might be because it advertises at about 108% improvement over the stock system... I don't know if that is just hot air under my skirt or what... Anybody got any other suggestions or knowledge of these systems?

Thanks Again!
