Description

The Tomei Expreme Unequal Length Header is engineered for EJ20 and EJ25 turbo Subaru engines, featuring a highly efficient 4-1 exhaust manifold design. The mandrel-bent tubing ensures optimal exhaust gas flow, contributing to improved engine performance and the characteristic OEM boxer engine sound beloved by enthusiasts. This comprehensive kit includes a 3-bolt stainless steel uppipe, specifically designed to be compatible with stock frame turbochargers, simplifying installation. The unequal length design of this header is known for its distinct exhaust note and can contribute to improved exhaust scavenging by reducing back pressure. Professional tuning is essential after installation to ensure the engine's computer can properly adjust to the altered exhaust flow, preventing lean or rich running conditions and maximizing performance gains.
