A muffler is designed to reduce the noise from your motor, but a performance exhaust muffler for Pontiac Firebird also delivers a refined rumble. When a muffler is defective, it reduces power and fuel economy and can even send toxic fumes into the cabin. A new Firebird muffler works in conjunction with your vehicle's exhaust system to deliver just the right sound, improved torque and increased horsepower.
