Hey, I am needing some info on two different exhaust setups. First is a set of long tube headers with a an ory pipe, high flow cat, and corsa catback system. Second is a set of LT's with true duals including two high flow cats, two magnaflow race mufflers, all the way through. Is there going to be a huge difference in performance gains between the two. Im sure some of you have tried both, and have dyno sheets from both setups. I just wanna see some proven numbers on both, and is it worth it for the whole dual setup.

depends on your plans. the dual will flow better but do you need all the extra flow. are you ever gonna do cam/head/fi?
