Remus 2019 Audi RS4 Avant Quattro B9 2.9L Turbo (DECA w/GPF) GPF-Back Exhaust

If you're looking to change the sound and feel of your 2019 Audi RS4 Avant Quattro with the 2.9L Turbo DECA engine and GPF, this Remus GPF-back exhaust system is a solid option. This system replaces the factory exhaust from the gasoline particulate filter (GPF) back, aiming to give your RS4 a more aggressive tone and improved flow without compromising emissions compliance.

Remus has a reputation for well-built exhaust systems, and this one is no exception. It's constructed from stainless steel to resist corrosion and ensure longevity, even in harsh driving conditions. The design focuses on optimizing exhaust gas flow, which can lead to a more responsive throttle and a deeper, sportier exhaust note that complements the performance of the RS4's twin-turbo V6. While it's a GPF-back system, meaning it works with your existing GPF, the improved internal design of the mufflers and piping can still make a notable difference in sound and performance characteristics.

Installation involves removing the factory exhaust components from the GPF rearward and fitting the Remus system. It's designed as a direct replacement, meaning no welding or cutting is typically required, making the installation process more straightforward. This system is a significant upgrade for owners who want to enhance the auditory experience of their high-performance Audi wagon.
