The HKS 65mm Stainless Steel Center Pipe Mid-Pipe is a high-performance exhaust component designed to optimize exhaust flow in the Subaru WRX STI from 2008 to 2014. Crafted from durable stainless steel, this mid-pipe reduces backpressure and thermal stress by increasing the mass and velocity of exhaust gases. Its design enhances engine efficiency, resulting in improved power, torque, and throttle responsiveness. Engineered with a focus on performance, quality, and value, this mid-pipe helps unlock the vehicle's full potential by allowing exhaust gases to exit more freely, thereby boosting overall engine performance and efficiency.

This mid-pipe is a direct replacement for the factory component on 2008-2014 Subaru WRX STI models. It is suitable for street and performance applications, providing a straightforward bolt-on upgrade that enhances exhaust flow. The kit includes the stainless steel mid-pipe and necessary mounting hardware for easy installation. Designed to work with the stock or aftermarket exhaust systems, it is ideal for enthusiasts seeking increased performance and a more aggressive exhaust note without extensive modifications.

Overview

Increasing the amount of exhaust flow is the first progressive step to increased engine performance and efficiency. The factory exhaust system represents a restriction in the stock configuration. By designing a system that increases the mass and velocity of exhaust flow, it allows for a reduction in backpressure and thermal stress, thus unleashing the engine's potential for increased power, torque, and responsiveness. All HKS exhaust systems are engineered with performance, quality, and value as primary goals. Through countless comprehensive efforts of flow analysis, dyno testing and tuning HKS is able to maximize horsepower gains throughout a broad powerband, while maintaining reasonable sound levels for street use. HKS Exhaust Systems that are designated for street use retain all factory emissions equipment and conform to the California Vehicle Code 95-decibel exhaust noise level limit. HKS exhausts systems are designed for a direct bolt-on fitment to the stock flanges and come with all the necessary gaskets and hardware to provide simple installation and long-term durability.
