Resonator Delete Exhaust Midpipe

The Integrated Engineering IEEXCK4 midpipe exhaust upgrade is engineered to transform the sound profile of your Audi B9/B9.5 S4 or S5 3.0T. By replacing the factory section that includes resonators with a high-flow, straight-pipe design, this upgrade delivers a more aggressive exhaust note, enhanced burbles, and sharper downshift sounds, making the car feel more alive. Constructed from premium 304 stainless steel tubing, the IEEXCK4 offers significant advantages in weight reduction and corrosion resistance, ensuring long-lasting performance. Reinforced mounting brackets are also included for extended service life. The kit includes all necessary hardware and clamps, with an estimated installation time of around 2 hours using standard hand tools. The midpipes feature a 63.5mm OD and 60.25mm ID. This midpipe upgrade is specifically designed for the Audi B9/B9.5 S4 and S5 models equipped with the 3.0T turbocharged engine, from model years 2017 through 2024. While the product aims for precise fitment using advanced 3D scanning and rapid prototyping, some users and installers have noted that the placement of the larger straight piping may not align as perfectly as factory components, though performance remains unaffected.
