APR Non-Resonated Midpipe Exhaust System for Audi SQ5 (B9) | MPK0009

The APR Non-Resonated Midpipe Exhaust System (MPK0009) is engineered to give your Audi B9 SQ5 a deeper, more aggressive growl by replacing the restrictive factory resonators. This system serves as a modular "bridge," allowing for a direct bolt-on fitment with the factory exhaust components or a seamless integration with the APR Rear Catback System for a full performance exhaust overhaul. By eliminating the center resonators and utilizing oversized, mandrel-bent 2.75" piping, this midpipe significantly reduces backpressure and enhances the 3.0T engine's natural acoustics.

Constructed from premium T304 stainless steel with a brushed finish and full TIG welding, the system is designed to withstand the high-heat environment of the SQ5 engine bay. It features precision-fit brackets and high-quality flex sections with interlocking liners to ensure a rattle-free, professional installation. Whether you are looking for a subtle increase in sound or the foundation for a high-horsepower build, this midpipe delivers verified power gains and a refined, sporty tone without compromising emissions compliance.
