Presenting our Turner Motorsport Performance Cat-Back Exhaust, tailor-made for your 4-cylinder F Chassis. Immerse yourself in an enhanced driving adventure as this meticulously engineered exhaust takes your B48-equipped car to exhilarating new heights. With an unwavering commitment to performance and quality, the Turner exhaust is crafted to unlock the full potential of your F chassis.

Experience a symphony of performance and sound, coupled with a visual upgrade through the quad exit exhaust tips that amplify the motorsport essence of your vehicle. Elevate your driving encounters with the Turner Motorsport axle-back exhaust - unleash the power, reveal the glorious sound, and capture attention wherever you go.

Incorporating their distinctive design principles, this exhaust produces a commanding, deep tone, revealing the bold personality of the revolutionary line of 4-cylinder turbo engines. Leveraging the factory valve control, the Turner axle-back ensures an exciting sound during acceleration, seamlessly blending the high-performance sound with daily driving convenience. Crafted from 1.25mm wall T304 stainless steel, Turner's exhaust boasts superior durability, corrosion resistance, and aesthetic appeal.

Designed with the customer in mind, the installation is a breeze, featuring a straight-forward slip joint and mounting locations. Your exhaust system includes all the necessary clamps and hardware for a hassle-free installation. Upgrade your f chassis with the Turner Motorsport axle-back and let every drive become a statement of power and style.

Upgrading the sound:

This exhaust allows you to turn up the volume and let the 4 cylinder boast its smooth and hearty exhaust tone. Let's be honest, what's the point of owning a f chassis 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 B48 sound!
