Performance Dual Cat-Back Exhaust Muffler System
A performance dual cat-back exhaust system replaces everything after the catalytic converter, upgrading your vehicle with dual exhaust pipes, performance mufflers, and exhaust tips.
Key Features
- Dual exhaust layout (split into two outlets for better flow)
- Stainless steel construction (durability + corrosion resistance)
- Straight-through muffler design (maximum performance sound)
- Mandrel-bent piping (smooth airflow, less restriction)
- Bolt-on installation (no welding in most cases)
Performance Benefits
- Increased horsepower & torque due to improved exhaust flow
- Better throttle response
- Reduced backpressure
- More aggressive engine sound and tone
Some systems can deliver 10–20 HP gains depending on the vehicle and setup
Sound Characteristics
- Deep, aggressive tone at idle
- Louder, sportier sound under acceleration
- Dual mufflers help balance sound across both exhaust sides
- Some systems minimize drone inside the cabin
Advanced systems (like CORSA) even use noise-canceling tech to eliminate drone while keeping aggressive sound outside. (GBP Performance)
Types of Dual Cat-Back Systems
- Straight-through muffler systems → loudest, best performance
- Chambered mufflers → deeper tone, less harsh
- Valved systems → adjustable sound (quiet ↔ loud)
- Dual rear exit vs side exit → style + sound direction

Cat-back systems are vehicle-specific, commonly available for:
- Sports cars (BMW M3, Camaro, Supra)

Always match:
