Review on High-Quality GM 12617944 Exhaust Manifold Gasket for Optimal Performance by Justin Herman

Revainrating 5 out of 5

ALWAYS USE OEM GASKETS ONLY. OEM ONLY. OEM ONLY. OEM ONLY.

As said above, ONLY use GM OEM Gaskets whether you are using a stock exhaust system, cheap or expensive exhaust manifolds. Fix leaks and pay for the right things the first time. Do not do that. cheap, don't do your project twice.

Pros
  • This is great
Cons
  • High price
