HKS SUPER TURBO MUFFLER 14+ Subaru WRX STi (EJ20) Catback Exhaust

HKS is a well-known name in the performance automotive world, particularly for their focus on enhancing engine sound and power. This Super Turbo Muffler catback exhaust system is built specifically for the 2014 and later Subaru WRX STi models equipped with the EJ20 engine. It's designed to replace the factory exhaust from the catalytic converter back, offering a more aggressive tone and improved exhaust flow.

Constructed from SUS304 stainless steel, this system is built to resist corrosion and handle the heat generated by spirited driving. The muffler design is a key feature, aiming to provide a deep, sporty sound without excessive drone inside the cabin, which is often a concern with aftermarket exhausts. The large-diameter piping and optimized muffler internals work together to reduce backpressure, potentially leading to better throttle response and a slight increase in horsepower. Installation is intended as a direct bolt-on replacement for the stock system, meaning no welding or cutting is typically required, making it a straightforward upgrade for enthusiasts looking to personalize their WRX STi's performance and sound profile.

When installing this catback exhaust, it's a good idea to have a helper and ensure you have the necessary tools for removing the old exhaust and mounting the new one. While it's designed for a direct fit, checking the alignment before fully tightening all connections can help ensure a clean installation and prevent rattles. This system is a significant upgrade for the EJ20 engine, enhancing both the auditory and performance aspects of your Subaru WRX STi.
