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

 Compatibility

Cat-back systems are vehicle-specific, commonly available for:

• Sports cars (BMW M3, Camaro, Supra)
• Trucks (Ford F-150, Silverado, RAM)
• Performance sedans

Always match:

• Engine size
• Model year
• Exhaust diameter

 What’s Included

• Mid-pipe section
• Dual mufflers
• Exhaust piping
• Tips (polished, black, or titanium)
• Clamps / hardware (varies)

 Why Choose a Dual Cat-Back Exhaust?

• Improves both performance and sound
• Enhances vehicle appearance (dual tips)
• One of the most effective bolt-on upgrades
• Widely used in both street and track builds
