Simons cat-backs

Simons cat-backs are a good choice for anyone who wants a sportier sound, better exhaust flow and a quality upgrade of the car’s original exhaust system. A cat-back system replaces the part of the exhaust located after the catalytic converter and gives the car a more complete exhaust setup without necessarily changing the downpipe or catalytic converter.

Simons is known for exhaust systems with focus on good fitment, robust construction and a more distinctive sound than the standard exhaust. A Simons cat-back system can give the car a sportier look while still being suitable for road use, tuning and performance builds.

By upgrading to a Simons cat-back, the exhaust can achieve freer flow than the original system. This can reduce restriction in the rear section of the exhaust and give the engine better working conditions, especially on cars with tuning, turbo, larger engine or other performance upgrades.

Many Simons cat-back systems are made from stainless steel or aluminised steel, depending on model and system type. This provides good durability and makes the systems suitable for cars used for daily driving, styling, trackday and motorsport. The choice of pipe diameter, silencer design and tailpipe has a major impact on sound, flow and the overall look of the car.

Simons cat-backs are available for many different car models and are often used on classic cars, newer performance cars and tuning projects. They are relevant for anyone who wants an exhaust upgrade that can both improve the car’s sound and give a sportier visual appearance.

Many systems are developed as model-specific solutions that fit the car’s original mounting points. This makes installation easier and ensures a clean fit when the system is correctly selected for the individual car model.

A Simons cat-back system is an obvious upgrade for anyone who wants more sound, better flow and a sportier exhaust setup. Together with the correct engine setup and other performance parts, a cat-back system can be an important part of a complete tuning or motorsport build.
