Review on 🚀 Improve Performance with ATP Automotive Graywerks 101140 Exhaust Manifold by Brad Blake

Good header. You can get the same quality from a resto catalog for more, but this one has the hardware. Mine wasn't warped as far as I could see and yes the molding inside is a BIT rougher than the original but it looks the same on the outside. Finished surfaces are fine. The factory thermal damper seems to work fine. The equipment is fine. Locknuts would be cool, but I can do the job. My box had a second layer that contained my pads and they were fine. It's great for my restaurant project that I drive 3 days a week.
