Review on 💨 ATP Automotive Graywerks 101122 Exhaust Manifold/Catalytic Converter: Efficient Exhaust System Upgrade by Cameron Novak

The quality has deteriorated since my last purchase in 2012. Does not include round metal O-ring. Does not include new exhaust studs. I had to use a pry bar and vise to bend the heat shield at the bottom to attach the gasket to the studs. Mounting to the midpipe was tricky - I recommend unscrewing at least the bracket and possibly the tuned pipe (don't forget to buy new exhaust spring bolts if you need to unbolt the tuned pipe). However, it actually fixed my p0420 code. The gaskets looked pretty poor, but seemed to provide an adequate seal. The car drives better than with a cracked exhaust manifold. Next time I'll take a Dorman collector. I think this part is at the end of its production line.
