FactionFab MLS Up-Pipe to Turbo Gasket | Multi-Layer Steel | Exhaust Gasket

Overview

The FactionFab MLS Up-Pipe to Turbo Gasket is a precision-engineered exhaust gasket designed to provide a reliable and durable seal between the up-pipe and turbocharger flange. This gasket is essential for Subaru enthusiasts looking to maintain optimal exhaust flow and prevent leaks in their turbo system, especially when upgrading or modifying exhaust components. Its robust construction ensures long-lasting performance under high-temperature and high-pressure conditions typical of turbocharged Subaru engines.

Crafted in Japan using advanced multi-layer steel (MLS) technology derived from head gasket design, this gasket stands out for its superior sealing capabilities. Unlike typical reusable gaskets that offer little to no compression, the FactionFab gasket features 30% compression upon installation, allowing it to conform perfectly to imperfect flange surfaces. The use of 304 and 430 stainless steel layers combined with a round fire ring design enhances durability and sealing efficiency, reducing the risk of exhaust leaks that can affect performance and reliability.

For Subaru owners, especially those running ported exhaust systems or larger diameter tubing, this gasket’s enlarged bore size accommodates these modifications without compromising the seal. The undercut intermediate layers allow proper crushing, ensuring a tight fit that maintains exhaust integrity and supports consistent turbo performance. This gasket is a practical upgrade for anyone seeking a dependable seal that matches or exceeds OEM standards, helping preserve power delivery and reduce unwanted noise or emissions.
