Cat Back Exhausts

Cat Back Exhausts replace the exhaust system from the catalytic converter rearward, depending on the vehicle layout. They are commonly chosen to change exhaust sound, improve flow, replace worn factory sections or support a performance-focused build without replacing the full exhaust system.

Brands such as Manta Exhaust, XForce, Invidia, Redback and Pacemaker offer cat back exhaust options across street, 4WD, performance and modified vehicle applications. The right system depends on the vehicle, engine, body style, pipe diameter, material, sound level and intended use.

Why Exhaust System Choice Matters

A cat back exhaust can change the way a vehicle sounds and feels. Some systems are designed for a deeper tone and daily drivability, while others are louder, freer-flowing or more performance-focused. Pipe diameter, muffler design and resonator layout all affect the final result.

Sound preference is personal, but the system still needs to suit the vehicle and application. A system that is too loud or poorly matched to the vehicle can become tiring for daily use.

Cat Back Exhaust Details That Matter

• Vehicle fitment: Match the system to the exact make, model, year, engine and body style.
• Pipe diameter: Choose a diameter suited to the engine and intended use.
• Material: Compare mild steel and stainless steel options where available.
• Sound level: Muffler and resonator design affects volume, tone and cabin drone.
• Tip style: Tailpipe finish and outlet design can change the rear appearance.
• Transmission and drivetrain: Some systems vary by gearbox or drivetrain layout.
• Road use: Consider local requirements and how the vehicle is used.

Choosing the Right Cat Back Exhaust

The easiest way to find the right cat back exhaust is to use our simple rego finder or manually select your vehicle. This helps narrow the product list to options suited to your vehicle, so you are not sorting through exhaust systems that may not match your engine, body style or rear layout. Always check the product page for any specific notes.

When comparing suitable options, consider the sound level, material, pipe size and whether the vehicle is standard or modified. Installation is also available if you would prefer your exhaust supplied and fitted.
