Simons cat-back exhausts for Audi are an ideal choice if you want a more sporty sound, improved exhaust flow and a solid quality upgrade compared to the car’s original exhaust system. A cat-back system replaces the entire exhaust from the catalytic converter and backwards, giving you a more complete solution without necessarily changing the downpipe or catalytic converter.
Simons is known for focusing on good fitment, durable construction and a more distinctive, yet still well-balanced sound. The systems are developed to fit specific Audi models, ensuring easy installation and an OEM-like fit. This makes them suitable for both daily driving and more performance-oriented projects.
By upgrading to a Simons cat-back system, you get freer exhaust flow compared to the original setup. This can reduce back pressure in the rear section of the system and give the engine better working conditions – especially on cars with a turbo, optimised software or other performance upgrades. The result is often a more responsive engine and a more engaging driving experience.
Simons cat-back solutions for Audi are typically supplied in stainless steel, ensuring long service life and good resistance to rust and harsh weather conditions. The design ranges from discreet solutions to more aggressive setups with larger tailpipes, so you can find a solution that matches both the car’s appearance and your personal preferences.
Whether you drive your Audi daily, on trackdays or as a project car, a Simons cat-back exhaust is an effective way to upgrade sound, appearance and performance – without compromising on fitment and quality.
