Description

The Off The Line Performance Catted Header is a precision-engineered exhaust manifold designed to address the torque dip and performance limitations of the FA20/24 engine platform. By utilizing stepped, equal-length runners and a 4-into-1 collector equipped with a "power bullet" flow enhancer, this header optimizes exhaust scavenging to deliver significant midrange power gains. Each unit is TIG-welded in the USA and features 100% 304 stainless steel construction for long-term durability. Technical specifications include CNC-machined 1/2-inch stainless steel flanges for a reliable seal and heat sink-equipped O2 bungs to prolong the life of your oxygen sensors. The design also incorporates an OEM-placed high-flow catalytic converter to balance performance output with emissions efficiency. Compatibility covers a wide range of vehicles, including 2013-2017 Scion FR-S/Toyota 86/Subaru BRZ, 2018-2025 Toyota GR86/Subaru BRZ, 2015-2025 Subaru WRX, 2014-2018 Forester, 2019-2024 Ascent, and 2020-2024 Legacy/Outback models.
