64-72 A-Body H-Bomb Crossmember Back Exhaust

The PYPES Performance Exhaust 64-72 A-Body H-Bomb Crossmember Back Exhaust is designed specifically for classic Mopar enthusiasts with 1964–1972 Dodge and Plymouth A-Body vehicles, including the Barracuda, Duster, Valiant, and Scamp. This complete bolt-on system provides an opportunity for restoration and modification while maintaining period-correct aesthetics.

The H-Bomb designation highlights the system's mandrel-bent tubing construction, which optimizes flow characteristics and minimizes turbulence compared to traditional crush-bent alternatives. This design is intended to enhance scavenging efficiency and reduce back-pressure, contributing to potential improvements in horsepower and torque across the RPM band.

Restorers and performance builders will find this bolt-on system beneficial for achieving a precise fit in A-Body chassis configurations. The options for stainless steel or aluminized steel construction ensure durability and resistance to corrosion and heat degradation, making it suitable for both street and strip applications.
