GReddy 03-08 Mazda RX8 63.5mm Dual Muffler Supreme SP Exhaust

GReddy is well-known for making performance parts that help drivers get more out of their cars. This Supreme SP cat-back exhaust system is built specifically for the 2004-2011 Mazda RX-8, aiming to improve its sound and flow. It replaces the factory exhaust from the catalytic converter back, giving your RX-8 a more aggressive tone and potentially better breathing for the engine.

This system features 63.5mm diameter piping, which is a common size for naturally aspirated rotary engines like the one in the RX-8, offering a good balance between improved flow and maintaining exhaust velocity. The dual muffler design helps manage the exhaust note, aiming for a deep, sporty sound without being overly loud or droney. The mufflers and piping are constructed from stainless steel, which is a strong material that resists corrosion and holds up well over time, especially important for exhaust components that are exposed to heat and moisture.

When installing a cat-back system like this, you're typically looking at a bolt-on process that doesn't require welding. It's a popular upgrade for RX-8 owners looking to enhance the driving experience. You'll want to ensure you have the necessary tools and potentially a helper for maneuvering the exhaust sections into place. The result is a well-built exhaust that looks and sounds the part for your RX-8.
