Description

The GrimmSpeed 34001 gasket is a 3-bolt up pipe gasket designed as a reliable replacement. Crafted from multi-layer steel with a stainless steel fire-ring, it is engineered to outperform standard OEM options and is 22% thicker than OEM gaskets. This construction ensures a tight seal, minimizing the risk of leaks and maximizing exhaust flow.

Installation requires ensuring that mating surfaces are clean and free of debris for optimal sealing. This gasket provides a direct fit without the need for modifications for specific 3-Bolt Up Pipe configurations. Upgrading to this gasket can result in improved durability and reduced gasket failure.
