Review on 🚗 Enhanced Performance Exhaust Manifold (Dorman 674-532) Specifically Designed for Geo Models by Rushabh Bear

Ordered a cracked exhaust on a 1995 Geo Tracker. Very inferior product compared to the OEM header. The quality of cast iron is very poor. No "post-processing" of the casting is required other than planing the mating surfaces. The inside of the runners is extremely rough and unfinished. The holes that mate with the block don't line up exactly. The iron used in casting contains a lot of impurities and deposits that are visible in many places. The bolt on the bottom flange side is NOT provided. This bolt is used to attach the lower support bracket to the manifold. You definitely need this rod. It will be almost impossible to reuse the one from the original header, so expect to have to drive around to find the M10 1.25 bolt. In the end, yes I did. It's wearable. The pads fit. It works out. I expect it to last? Not really, but that's on a car with >300,000 miles on it, so it really shouldn't take long.
