Product Details

This GReddy Supreme SP cat-back exhaust system is built for your 2009-2014 Acura TSX. What you get in the box is the complete cat-back assembly, including the piping, muffler, and all necessary hangers and hardware for installation. This system replaces your factory exhaust from the catalytic converter back, aiming to improve exhaust flow and give your TSX a more distinct sound.

The Supreme SP line from GReddy uses 63.5mm (2.5 inch) diameter piping, which is larger than stock, allowing exhaust gases to exit the engine more freely. This can lead to a slight improvement in throttle response and overall engine performance. The muffler itself is constructed from polished stainless steel for a clean look and good durability. It's designed to offer a sportier exhaust note without being overly loud or droney for daily driving. GReddy is known for its well-built exhaust components, and this system is designed to fit right onto your TSX without major modifications.

When installing a cat-back exhaust, it's always a good idea to have a helper, as some sections can be a bit unwieldy. Make sure to check the included hardware and compare it to the parts list before you begin. This system is designed to bolt up to the factory catalytic converter, simplifying the installation process. You'll notice a different sound and potentially a bit more responsiveness from your engine once it's on.
