Exhaust Manifold Mod

MoparMike1974, I do believe the Slant does like to breath. After I added the Super Six set-up on my ‘70 Dodge Slant6 I added a set of Hooker 3 into 1 headers into 2.25” real dual exhaust system with “H” pipe. Back to a pair of glass pack mufflers all the way to back of car capped with bright tips. Gives it a sound like a mild small block at Idle. Until you drive off then it does sound like a six.
