Review on ATP Automotive Graywerks 101253 Manifold by Corey Vaz

ATP Graywerks Model 101253 is a well made, very clean and consistent casting with a proper and accurate porthole. Haven't installed it yet but looks very good value for money. In contrast I have previously purchased a DORMAN 674509 which unfortunately was a very poor quality sloppy casting with lots of excess body material which narrowed the exhaust ports and port. Holes that were off center and significantly narrowed the connections (I immediately sent Dorman back for full credit including shipping as a defective part with 6 photos documenting quality control issues with the Dorman unit). I am very happy to recommend ATP Graywerks 101253 to any other auto repair DYI enthusiast. A good product!
