MagnaFlow SYS C/B 09 Audi S5 4.2L V8 Coupe

Magnaflow is well-known for making exhaust systems that give vehicles a distinct, powerful sound and improved performance. This cat-back system for your 2008-2012 Audi S5 with the 4.2L V8 engine is designed to do just that, giving your car an aggressive character that will definitely get noticed. It replaces your stock exhaust from the catalytic converter back, so you're getting a complete performance upgrade for the entire rear section of your exhaust.

This system features 2.5-inch diameter, fast-flowing mandrel-bent main piping. It runs through three straight-through mufflers, which help create that signature Magnaflow sound. The system exits at the rear with quad split tips, each 3.5 inches wide, polished, double-walled, and angle-cut with a folded edge. This setup is dyno-proven to enhance performance and tuned to deliver an aggressive exterior sound while keeping the interior sound at a moderate level. Magnaflow uses extensive 3D scanning and precision robotic manufacturing to ensure this system fits your S5 right, making installation a straightforward DIY job.

Built from durable, corrosion-resistant stainless steel, this exhaust system is made to last and is backed by Magnaflow's limited lifetime warranty. It's a lightweight, high-performance design that offers a racing-inspired sound, truly changing the auditory experience of your Audi S5.
