5.7L EXHAUST MANIFOLD KIT D/W TRUCK
Manifold Kit that allows installation of Most 5.7L Gen III Hemis into 1972-1993 D/W Dodge Pickups & Ramchargers. These Manifolds have a 2 1/2" exit opening which makes them much more free flowing than normal 5.7L DR truck Manifolds. Kit include 2-New Cast Iron Exhaust Manifolds, 2-Oxygen Sensor Weld-In Bungs, and 2-Exhaust Flanges. Most new engines, we reuse the factory bolts and gaskets. This Kit allows your exhaust shop to run a 2 1/2" exhaust pripe to manifolds, Ball Flare your tubing, Add the 2 Oxygen Sensor Bungs and Bolt them up.
That is about as trick and custom as you can get
