Product Description

MagnaFlow 16724 is a Street Series crossmember-back dual exhaust engineered for the 1961-1964 Chevrolet B-body platform--including Impala, Bel Air, and Biscayne. Using mandrel-bent 2.5" stainless tubing and dual straight-through mufflers, it frees up exhaust flow while delivering MagnaFlow's signature deep tone. The system is designed as a bolt-on upgrade that follows factory hanger locations and exits at a dual split rear, capped with polished 3.0" angle-cut tips.

Because it's crossmember-back, the kit connects behind the crossmember and retains the vehicle's front pipes and manifolds (or requires suitable adapters if headers are installed). The geometry has been developed for OEM-style chassis layouts across sedans, wagons, hardtops, and convertibles. Confirm your vehicle's manifold/collector size and hanger condition prior to installation for best results.
