Standard exhaust systems aren't made for performance vehicles, as they limit the engine's ability to breathe and curb your car's horsepower. The Firebird exhaust headers at AutoZone have the opposite effect, enhancing your vehicle's performance while outlasting other manifolds that are made from low quality materials. Come to AutoZone and let our friendly, helpful staff find you the parts you need. Order online and then head over for Same Day Store Pickup, and use our Loan-a-Tool program to make sure your header gets installed properly.
