GrimmSpeed Equal Length Exhaust Header 2022-2025 WRX

Description:
This is GrimmSpeed's Equal Length Header and has been designed to provide the turbocharger with an uninterrupted flow of exhaust gases to greatly improve the spool response while increasing the horsepower, the torque, all while saving weight. The equal-length layout will produce an aggressive, race-inspired exhaust tone throughout the entire RPM range, and makes for an excellent bolt-on modification. This header will work with the factory turbocharger or factory-like aftermarket turbochargers. Our attention to detail during development and overall exhaust knowledge allow us to make the best possible upgraded version of the factory alternative. After isolating the inadequacies of the OEM exhaust manifold, we were able to create a replacement that’s leagues above.

Features:
- 304 stainless steel construction
- True Equal-length collectors
- Innovative Cast Merge Collector: Low restriction inlet and outlet, smooth flow and consistent performance
