This is the Invidia Equal Length Race Exhaust Manifold. This type of manifold is ideal for those aiming to surpass large horsepower figures that would otherwise be limited by the flow capacity of the factory exhaust manifold. Designed for those targeting 600+ horsepower and beyond, this manifold can handle high power levels thanks to its robust construction and innovative design.

Performance and Compatibility

The manifold features a 2-bolt up-pipe flange, making it suitable for upgrading to an external-style up-pipe or accommodating some rotated turbo setups. Additionally, the smooth bends in the manifold design ensure an unobstructed flow path for exhaust gases, allowing the engine to exhale more efficiently. This design is particularly beneficial for those with moderate bolt-ons, providing a significant boost in performance by optimizing exhaust flow.
