Upgrading the sound:

Our exhaust allows you to turn up the volume and let the B46/B48 boast its smooth and hearty exhaust tone. Let's be honest, what's the point of owning a B48 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 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 B48 sound!

How the cat-back is designed:

To create a cat-back exhaust for this incredible vehicle the upgrade happens right at the downpipe. Turner replaced the factory components with oversized 3.0" T304 stainless steel piping. The true 3.0" exhaust makes its way through the center and rear of the car without the center muffler or resonator to keep the flow to a maximum! With smooth mandrel bent transitions, this exhaust passes perfectly under the rear subframe for a factory equivalent fit. Positioned in the rear of the car is Turner's signature B46/B48 muffler with a beautiful inlet and outlet piping that creates the perfect exhaust tuning. Featuring relief cut slip joints and fabricated sheet metal brackets the exhaust can be fully adjusted and mounted seamlessly in the factory locations. Dual 3.0" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.

Optional OBD Plug-In:

The factory-valved muffler is not only controlled by different driving modes like comfort, sport, and sport plus but the RPM also plays into whether the valves are opened or closed. If you are looking for a solution to define whether your exhaust valve is fully opened or closed then you should look into adding an OBD plug-in that features Bluetooth valve control from your phone. During testing, the best way to choose whether your valve is open or closed for your sound preference is through an OBD-linked application on your phone. Included in this kit are optional OBD extensions to not only gain diagnostic function but also gain the ability to influence widgets on your vehicle such as valve position on your valved muffler.
