1997-2001 Buick Park Avenue 3.8L Exhaust Manifold 4 Cyl W/ Heat Shield 674-509

Product Overview:
1.Exhaust headers are a key upgrade for boosting engine performance by improving airflow. Unlike restrictive factory exhaust manifolds, performance headers give each cylinder its own dedicated exhaust path, reducing back pressure and improving exhaust flow.
2.By minimizing exhaust interference between cylinders, headers help increase horsepower and torque. When paired with a high-performance cold air intake and a cat-back exhaust system, this setup removes engine restrictions—allowing your vehicle to perform at its full potential.
