Installation Notes and Tips

Verify year, make, model, and configuration before ordering, especially for vehicles noted with or without an integrated intake manifold. Compare the existing manifold, outlet style, and mounting points to the vehicle-specific fitment notes. For best results, inspect the mating surfaces, fasteners, and exhaust connections before installation.

Quality Assurance

ATP Parts designs exhaust manifolds to match original part fit and function, helping restore the exhaust system by eliminating leak points caused by failed factory components.
