Upgrading the sound:

Our exhaust allows you to turn up the volume and let the S55 roar a hearty exhaust tone. Let's be honest, what's the point of owning a S55 if you're not going to upgrade the exhaust? Our signature muffler design allows you to transfer the exhaust valve from your factory system directly onto your new Turner system. The Turner exhaust signature muffler design allows for two flow paths that change both tone and volume. With the vehicle in comfort mode, the valves remain closed, with the closed valves the exhaust system allows the gasses to flow through the muffler toning down the volume and giving a more refined exhaust note. While in driving modes sport or sport+ the valve opens and the flow path changes to a "straight flow path" essentially turning into a straight-piped exhaust for the least amount of restriction and the most amount of twin-turbo S55 sound!

How our axle-back is designed:

To create a axle-back exhaust for this incredible vehicle the upgrade happens right after the factory secondary cats. We replaced the factory components with dual 2.5" free-flowing stainless steel piping. The twin pipes make their way through the center and rear of the car without the center muffler to keep flow to a maximum! With smooth mandrel bent transitions our exhaust passes perfectly under the rear subframe for a factory equivalent fit. Positioned in the rear of the car is our signature F87 muffler with beautiful inlet and outlet piping that creates the perfect exhaust tuning. Featuring relief cut slip joints and oe-style hangers the exhaust can be fully adjusted and mounted seamlessly in the factory locations. Quad 4.0" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.

The Turner Motorsport E60 N52 3.0" T304 Stainless Steel Axle-Back & Midpipe Exhaust System is a direct-fit performance exhaust replacement designed to eliminate factory exhaust restriction and enhance the acoustic profile of the BMW N52 engine.

The restrictive OEM muffler and resonator restrict exhaust gas evacuation and suppress the engine's natural exhaust note. The Turner Motorsport system replaces these restrictive factory components with a CNC mandrel-bent 3.0-inch straight-through assembly, minimizing backpressure and accelerating exhaust gas flow while maintaining emissions compliance by retaining all OEM primary and secondary catalytic converters.

3.0-inch straight-through design T304 stainless steel with 1.25mm wall thickness CNC mandrel-bent with 100% hand TIG welding Brushed stainless steel body with laser-etched Turner branding on the tips Integrated stepped, slash-cut outlets Rigid sheet metal brackets with TIG-welded hangers utilizing OEM mounting locations Includes two stainless steel AccuSeal clamps and two 50mm sleeve-style exhaust clamps for leak-free sealing
