Cobb 17-21 Volkswagen GTI (MK7.5) USDM Cat-Back Exhaust

This is the COBB Cat-Back Exhaust system for your 2017-2021 Volkswagen GTI (MK7.5) USDM model. It's designed to replace the factory exhaust from the catalytic converter back, offering an improved sound and better exhaust flow. If you're looking to give your GTI a more aggressive exhaust note and potentially free up a little power, this system is a solid choice.

COBB built this cat-back system using 3-inch diameter, mandrel-bent 304 stainless steel tubing. Mandrel bending means the pipe maintains its diameter throughout the bend, which is crucial for smooth exhaust gas flow. The stainless steel construction is chosen for its strength and resistance to corrosion, meaning it should hold up well over time, even in areas with harsh weather. The system features a dual-muffler design that COBB tuned to provide a deeper, more satisfying exhaust tone without being overly raspy or droney at cruising speeds. It also includes polished 4-inch double-wall tips that give the rear of your GTI a cleaner, sportier look.

When installing this cat-back exhaust, you'll find it's designed as a direct bolt-on replacement for the factory system, meaning no welding or cutting is required. All the necessary hardware and gaskets are included to make the installation as straightforward as possible. You'll want to refer to the manufacturer's installation instructions for specific details on mounting and tightening procedures to ensure a proper seal and secure fitment.
