Should I just start removing things like the resonator, and or rear cats, and leave the stock muffler, or just have a local shop build me a removeable exhaust, without the rear cats, and resonator, and a dual in dual out magnaflow? Or do I really need two smaller mufflers? I can get away with emmissions for now, which is why I was thinking of keeping the original exhaust, just bolt it right back on if need be. Than again, I still have the stock mid pipe with all 4 cats from my cobra, just collecting dust(never needed to put it back on), and the car is gone. I am leanning towards duals, no rear cats, and the dual in dual out magnaflow. Anybody see any problems with this setup? Thanks in advance, chris
