Magnaflow Cat-Back Exhaust System for 10-12 Audi S4 3.0L Supercharged

This performance exhaust system enhances vehicle dynamics by providing a powerful, resonant exhaust note while delivering dyno-proven improvements in performance. Constructed from durable, corrosion-resistant stainless steel, it is engineered to withstand extensive use while maintaining its functionality and aesthetic appeal. The design incorporates fast-flowing, mandrel-bent 2.25-inch main piping paired with a 3-inch straight-through muffler to ensure optimal exhaust flow.

With a quad split rear exit featuring 3.5-inch polished welded-on double wall angle cut folded edge tips, this system not only looks impressive but also contributes to a moderate exterior and mild interior sound level. The cat-back configuration replaces the stock exhaust components from the catalytic converter back, ensuring a seamless fit and streamlined installation process.

This system is produced using CNC precision robotic manufacturing techniques, which guarantee a direct-fit design tailored for specific Audi models. Backed by a limited lifetime construction warranty, this exhaust system is built for long-lasting performance.
