Invidia 2002-2021 Subaru WRX/STi Equal Length Racing Manifold Header

Introducing the Invidia Equal Length Race Exhaust Manifold, a powerhouse solution designed for enthusiasts aiming to achieve substantial horsepower figures beyond the limitations of the factory exhaust manifold. Tailored for those pushing 600+ horsepower and beyond, this manifold is crafted with a 304 stainless steel construction, ensuring durability for years to come.

With a focus on performance, the equal-length design of this exhaust manifold is ideal for enthusiasts looking to optimize exhaust flow. The inclusion of a 2-bolt up-pipe flange caters to those upgrading to an external-style up-pipe or considering rotated turbo setups, providing versatility for various configurations.

Smooth bends in the manifold design create an unobstructed flow path for efficient exhaust gas expulsion, particularly beneficial for those with moderate bolt-ons. The built-in O2 sensor bung adds convenience, while the inclusion of new exhaust manifold studs ensures a seamless installation process.

Designed for fitment in 2004-2021 Subaru WRX STi, 2006-2014 Subaru Impreza WRX, and 2002-2005 Subaru Impreza WRX (with a 2.5L oil pan), this exhaust manifold features equal-length runners and a 2-bolt style up pipe with 1.65" inch diameter runners.

Experience a departure from the traditional boxer rumble, as the equal-length design of the Invidia Race Exhaust Manifold creates an aggressive 4-cylinder race-inspired sound. Explore the possibilities for your Subaru WRX or STi and elevate your performance ambitions with this precision-crafted exhaust manifold.
