Bolt-On Dual Exhaust Adapter


This is the quickest, easiest, and most affordable method of installing dual exhausts on your flathead Mopar. You need a 1 1/2″ or 2″ hole saw to open up the bottom of your manifold and then you simply bolt on the second dump using the four bolts that hold the manifolds together. A do-it-yourself kit with the two flanges and a gasket is $75. You supply the exhaust tube and do your own welding which allows you to position the dump wherever it suits your vehicle. A completely welded unit is $150. Available for both the small family of engines, 218/230 and their larger cousins, 251/265. Prices include shipping to lower 48 US addresses. Add $25 to Canadian locations. Adding a second dump doubles the outgoing flow rate while allowing the use of either single or dual exhausts without a balance tube.
