Review on High-Quality ATP Automotive Graywerks 101111 Exhaust Manifold: Maximum Performance Guaranteed by Jon Cherian

Revainrating 5 out of 5

Do not use the gasket supplied

I installed this a few weeks ago and only recently noticed a hissing noise under the hood. After tracing it, I found that the gasket wasn't tight on the center stud. I have a factory service manual and made sure to follow the recommended tightening procedure when installing, so I'm not sure why this could have happened. I remember when I installed it it didn't sit as straight as I would have liked. Otherwise the collector himself was fine.

Pros
  • Industry Best Limited Lifetime Warranty
Cons
  • Questionable Senior Purchase
