Introducing our Turner Performance Cat-Back Exhaust for your G20 M340! Precision-crafted exhaust that elevates your driving experience with a new level of excitement. Designed with our commitment to performance and quality, this exhaust is meticulously engineered to unleash the true potential of your M340. In tandem with performance and sound, our cat-back exhaust enhances the visual aesthetic with upgraded quad exit exhaust tips that complement the overall motorsport nature of the M340 and replace the fake factory exhaust tips. Upgrade your driving experience with our cat-back exhaust for your M340! Unleash the power, bask in the glorious sound, and turn heads wherever you go.

Using our signature design principles this exhaust is crafted to deliver a deep, authoritative tone that reveals the true rowdy attitude of the M340. Designed to utilize the factory valve control our cat-back provides an exhilarating sound during acceleration without compromising the daily driving amenities. Our exhaust is manufactured of 1.25mm wall T304 stainless steel for superior durability, corrosion resistance, and aesthetics. Designed with the customer in mind it features a straightforward bolt-on installation utilizing factory slip joints and mounting locations and includes are clamps and hardware necessary for installation.

Upgrading the sound:

Our exhaust allows you to turn up the volume and let the B58TU boast its smooth and hearty exhaust tone. Let's be honest, what's the point of owning a B58 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 B58 sound!

Upgraded aesthetics:

From the factory, the G chassis comes equipped with fake or imitation exhaust tips, our Turner exhaust allows you to remove the imitation tips from the vehicle and sport a set of 4 true exhaust tips giving that upgraded motorsport styling.

How the cat-back is designed:

To create a cat-back exhaust for this incredible vehicle the upgrade happens right at the downpipe. We replaced the factory components with our full 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 our exhaust passes perfectly under the rear subframe for a factory equivalent fit. Positioned in the rear of the car is our signature B58 muffler with 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. Quad 3.5" exhaust tips are optioned to fill out the open space in the rear diffuser and complete the rear profile of the vehicle.
