FactionFab MLS Head to Exhaust Manifold Gasket | Multi-Layer Steel | High-Performance Exhaust Gasket

Overview

The FactionFab MLS Head to Exhaust Manifold Gasket is a precision-engineered sealing solution designed to maintain the integrity and performance of your Subaru’s exhaust system. Crafted for enthusiasts who demand durability and reliability, this gasket ensures a tight, leak-free connection between the cylinder head and exhaust manifold. It is ideal for those upgrading their exhaust or running ported heads where maintaining a perfect seal is critical to performance and longevity.

Built using advanced multi-layer steel (MLS) technology derived from head gasket designs, this gasket features a robust 304 and 430 stainless steel construction. Manufactured in Japan, it reflects a high standard of quality and engineering precision. The design incorporates a 30% compression rate upon installation, significantly higher than OEM standards, to accommodate imperfect sealing surfaces and reduce exhaust leaks effectively. This approach surpasses competitors’ reusable gaskets, which often lack compression, ensuring a more reliable and lasting seal.

Subaru owners upgrading their exhaust systems or running ported heads will appreciate the enlarged bore size that fits larger tubing and ported exhaust configurations. The round fire ring design promotes superior sealing compared to traditional U-shaped rings, preventing leaks that can affect performance and emissions. This gasket’s durability and fitment precision help maintain optimal exhaust flow and engine efficiency, making it a practical upgrade for Subaru enthusiasts focused on performance and reliability.
