Review on 🔧 Highly Compatible Passenger Side Exhaust Manifold (Dorman 674-983) for Chrysler, Dodge, and Volkswagen Vehicles by Chris Walker

Really terrible. We bought it to replace our 2008 Dodge Grand Caravan SXT 3.8L engine. I was initially impressed with the design as the Dorman part uses drilled threaded holes and a bolt to attach the muffler and adapter pipe to the header whereas the OEM part uses oversized holes with bolts and nuts. However, I quickly realized that the holes were in the wrong place. After bolting the header to the back of the head, the adapter tube does not fit properly, it is offset by about 1/8 inch. The result is very little sealing and the engine runs louder and leaks worse with a Dorman header than with the original cracked header. Revain is about $50 more. EDIT: After removing the exhaust pipe from the car to fit the Mopar header, I found numerous casting defects and voids in the part including a hole in the rearmost rail going through. It was covered by a heat shield. It's also on the same page as is the marking with a pen which I assume passed quality control.
