66-74 Dodge B-Body 2.5in Header-Back Exhaust

The 66-74 Dodge B-Body 2.5in Header-Back Exhaust from PYPES Performance Exhaust is designed for classic Mopar enthusiasts looking to enhance their vehicle's performance and sound. This exhaust system is a perfect upgrade for first-generation B-Body platforms, including the Charger, Coronet, and Road Runner models, making it suitable for street builds and restorations.

Constructed from mandrel-bent tubing with a 2.5-inch diameter, this header-back design aims to improve exhaust flow by reducing turbulence and backpressure. The system is engineered to connect directly to existing headers, allowing for compatibility with both original and aftermarket cylinder head combinations, while maintaining modern exhaust flow characteristics.

This exhaust system is ideal for both mild street engines and higher-output 340/360/440 combinations commonly found in B-Body restorations. Installation is straightforward with basic hand tools, and it fits vehicles with stock or mildly modified engine bays, although chassis-notching may be necessary for heavily lowered cars or extreme suspension setups.
