Anyone ever try it? Been thinking about getting an extra OEM exhaust can and making a dual set up with OEM mufflers. I want some extra performance for a MSD set up, but would like the maintenance free set up of baffles instead of packing. I know i would have to equalize the headers. Should be something easy for a muffler shop to do. Just wondering if anyone has tried it and what kind of gains versus Muzzys were seen?
