HKS RX8 75mm Single Ti-Tip Hi Power Cat-back Exhaust (SUS304 NO COATING)

If you're looking to give your Mazda RX8 a more aggressive sound and improved exhaust flow, this HKS Hi-Power cat-back exhaust system is a solid option. Designed specifically for the RX8, this system replaces the factory muffler and piping from the catalytic converter back, aiming to enhance the rotary engine's distinctive tone and potentially free up a bit of horsepower. The goal here is a sportier exhaust note that lets you hear the engine working, especially under acceleration.

This cat-back is constructed from SUS304 stainless steel, which is known for its strength and resistance to corrosion, meaning it should hold up well over time. It features 75mm diameter piping, a larger size than stock, which helps reduce backpressure and allows exhaust gases to exit more freely. The system culminates in a single Ti-tip, which is titanium, adding a touch of visual flair to the rear of your RX8. Unlike some finishes, this system uses a natural SUS304 finish with no coating, so you'll see the material itself.

Installation involves removing your stock cat-back section and bolting this one in its place. Because it's a cat-back system, it's designed to connect to your existing catalytic converter. You'll want to ensure all connections are secure to prevent leaks and get the best sound and performance from the system. This HKS exhaust is a popular choice for RX8 owners wanting a noticeable upgrade in both sound and appearance.
