What material is the HKS Sport Cat-Back Exhaust made from?

This exhaust system is constructed from SUS304 stainless steel. This material is chosen for its strength and resistance to corrosion, which is important for exhaust components exposed to heat and the elements.

What is the main benefit of a cat-back exhaust system?

A cat-back system replaces the exhaust components from the catalytic converter back to the tailpipe. This typically results in improved exhaust flow, a sportier sound, and can contribute to better engine breathing and throttle response.

Does this exhaust system come with all the necessary hardware for installation?

This cat-back exhaust system is designed to bolt onto your existing catalytic converter. While it includes the main exhaust components, it's always recommended to check the manufacturer's installation guide or consult with a professional to confirm if any additional hardware or gaskets are needed for your specific vehicle.

Product Details

HKS is well-known for making performance parts for Japanese sports cars, and their Sport Cat-Back Exhaust for the 2003-2006 Mitsubishi Lancer Evolution (EVO 8/9) is a prime example. This system is designed to improve the exhaust flow from your catalytic converter back, aiming for a more aggressive sound and potentially better engine breathing. If you're looking to give your EVO a more distinct exhaust note and a sportier feel, this cat-back system is a solid choice.

Crafted from SUS304 stainless steel, this exhaust is built to resist corrosion and handle the heat generated by spirited driving. The piping diameter is optimized for the EVO 8/9 platform to help reduce backpressure compared to the stock system. This means your engine can expel exhaust gases more freely, which can contribute to improved throttle response and a more satisfying exhaust tone. The Sport version typically offers a noticeable sound increase over stock, giving your EVO that aggressive growl you might be looking for without being overly obnoxious for daily driving.

When installing this cat-back system, you'll find it's designed to bolt up to your existing catalytic converter, making the installation process more straightforward. It replaces the factory muffler and piping from that point back. You'll want to ensure you have the necessary tools and possibly a helper for this job, as exhaust components can be heavy and awkward to maneuver. The result is a well-built exhaust system that complements the performance pedigree of the Lancer Evolution.
