GReddy 09-10 Mazda RX8 CS-GTS Exhaust

GReddy is well-known for making performance parts that help drivers get more out of their cars, and this CS-GTS cat-back exhaust system is a prime example of that focus for your 2004-2011 Mazda RX-8. This system replaces the factory exhaust from the catalytic converter back, aiming to give your RX-8 a more aggressive sound and potentially free up a bit of horsepower by reducing backpressure. If you're looking to change the character of your RX-8's rotary engine's song, this is a solid way to do it.

This cat-back system is constructed from SUS304 stainless steel, which is a strong material that holds up well against corrosion, especially important for exhaust components that see a lot of heat and moisture. The piping diameter is 70mm, which is larger than stock, allowing exhaust gases to flow more freely. The muffler design is specifically tuned to produce a deep, sporty tone that complements the unique sound of the RX-8's rotary engine without being overly raspy or droney at cruising speeds. GReddy has put a lot of thought into the resonance and tone, aiming for a sound that's exciting during acceleration but still manageable on the highway.

When installing this system, you can expect it to fit right onto your RX-8, connecting to the factory catalytic converter. The kit includes all the necessary piping, the muffler, and the exhaust tips, along with the required hangers and clamps for a complete installation. While it's a cat-back system, meaning it bolts up to your existing catalytic converter, it's designed to be a direct replacement for the factory muffler and rear section. This makes it a straightforward upgrade for those wanting to enhance both the sound and the performance feel of their RX-8.
