Cat-Back Exhaust System

Cat-Back Exhaust System

The MagnaFlow competition series cat-back exhaust is the perfect replacement for your old exhaust. It will significantly improve your torque, engine performance and vehicle horsepower. This means that you will be saving on fuel and gas costs. It is a highly valuable addition that will systematically boost your vehicle's resale value.

Straight-Through Muffler

Straight-Through Muffler

The system includes a straight-through muffler that features a perforated stainless steel core. It has a layer of stainless steel wool that insulates the core to prevent blowouts by absorbing excess heat and sound waves. The design runs through end to end with no louvres, baffles or chambers to restrict air flow.

Unrestricted Exhaust Flow

Unrestricted Exhaust Flow

The exhaust system tubing maintains the same diameter throughout. This mandrel bending allows a smooth and unrestricted flow of gases and waves which prevents backpressure. Ultimately, it boosts the exhaust and engine performance.
