    Magnaflow Manifold Catalytic Converters

    Similar to direct-fit converters that bolt directly into a vehicle's exhaust line, manifold catalytic converters are integrated into a vehicle's exhaust manifold, a component that collects exhaust gases from multiple cylinders into a single pipe. Because of their specialized design and fitment for specific vehicle models, manifold converters are typically more expensive than direct-fit or universal converters. In terms of installation, this type of converter requires the entire exhaust manifold to be removed and replaced.
