:Dok switching from tti step headers to 1 7/8 race header, motor made 583 hp with the steps , has anyone tested or dynoed the race headers with 3 inch x pipe and muffler against 3.5 x pipe and muffler to see which is the best or anything similar?
yeah I know they are not specified to dodge stuff but has anyone ever ran these mufflers on a mopar product? wanting something diff than the normal sounding exhaust?
