3.5" High Flow Stainless Single Midpipe 

 Introducing the best-sounding exhaust setup for the BMW M3 & M4 S55 platform. A high flow performance midpipe that converts the dual midpipe stock setup into a single midpipe. The key to making the S55 engine sounding better is to increase the diameter of the exhaust pipe in a single section, as the 2.5-inch dual midpipe stock setup doesn't offer enough volume per exhaust pipe to deliver a deep note. Large diameter piping equates to a deeper and more aggressive exhaust notes. By also making the midpipe high flowing it allows for a quicker turbo spool, this factor increases the power of the car up to 18hp (13 kW) and 30 ftlb ( 40nm). Using the latest 3D scanning technology we have developed a single mid-pipe to fit both the F80 M3 and the F82 M4

Underbody Brace

• To accommodate for the larger diameter piping we have designed an underbody brace that increases the room available for exhaust piping. The OEM brace is to flat and doesn't allow for a larger exhaust piping diameter than 3 inches. The included underbody brace allows for extra clearance, reduces the dreaded in cabin droning from the exhaust touching against the brace and the car retains its OEM rigidity.
