I see some of the axle back exhausts from certain manufacturers are the same for the 2.3 and 2.7. Other brands have specific 2.3 vs 2.7 which looks like slight muffler differences. Has anyone installed a 2.3 specific axle back exhaust on a 2.7 truck? I'm guessing it would fit but sound different since the muffler is not specifically picked for it.
