Upgrading the sound:

This 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 an S55 if you're not going to upgrade the exhaust? Turner's 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 eco or 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!

Turner Motorsport F87 Skid Plate - Milled Finish

The F87 M2 Competition & M2 CS models are simply amazing to drive; don't let road debris keep you from enjoying the moment. These cars have so much packed under the hood to get you this experience it causes the oil cooler to be placed face-down to the road. This makes the cooler an easy target for impact, which can prove catastrophic as the stock belly pan is designed from a flexible plastic material. We've heard stories of small branches, scrap pieces that fell from trucks to large ice chunks impact the cooler immediately draining the car of its oil. If you don't catch this right away this could cause serious internal engine damage due to oil starvation.

Turner's in-house engineering designed a skid plate to protect your oil cooler from these unfortunate situations while maintaining factory aerodynamics and fitment. The idea was to design something much stronger yet that still keeps the weight to a minimum. The Turner skid plate weighs slightly more than the plastic OE piece, making the Turner plate the lightest metal option on the market. This skid plate requires no modification and mounts using the existing factory hardware. Using a trim seal to press against the oil cooler allows the airflow to pull heat from the cooler the same way the OE belly pan was designed.

Features:

No cutting, drilling, or modification required
1/8” 5052 Aluminum skid plate construction.
10 Ga 5052 Aluminum side pieces to save weight.
Increased ground clearance.
Integrated frame-mounted support bracket for maximum strength.
Included bulb seal maintains oil cooler efficiency.
Retains factory air duct for oil cooler.
Maintains wheel liner mounting positions.

The Akrapovic Evolution exhaust systems for the BMW F30 340i & F32 440i are the result of the perfect integration of expertise, the best technology, and the use of the finest materials. Made of austenitic stainless steel, these systems feature a newly developed layout with two central link pipes replacing the single stock pipe, a new muffler design, and carbon fiber tailpipes.

This Akrapovic Evolution exhaust improves upon the stock exhaust system of the BMW 340i in numerous areas. The first visible improvement is the additional power of 4 HP (at 6400 rpm) and 6.3 Nm (at 2550 rpm). The range between 2.000 rpm and 3.500 rpm  was particularly improved. A noticeable improvement can also be observed at high RPM where the Evolution gives more power. This sporty elegance makes this Bavarian machine stand out from the rest and offers the taste of a more powerful version, accentuated with the additional power gains and weight losses of the Evolution system. The dual-mode ECU-controlled valve exhaust from Akrapovic offers stock-level sound at normal cruising, and a joyful deep sporty note when driving the 340i more dynamically. The Evolution systems replace the stock exhaust from the catalytic converters back.
