The 70–74 Mopar E-Body 2.5-inch Header-Back Exhaust (SME11S) is a complete stainless steel exhaust system engineered for classic Mopar muscle cars from the peak performance era. This header-back configuration delivers improved exhaust scavenging and flow characteristics while maintaining the factory mounting points and structural compatibility of your E-Body platform.
Featuring a 2.5-inch diameter pipe with matching 2.5-inch tips, the system balances performance gains with street-friendly characteristics. Stainless steel construction resists corrosion far longer than factory steel, critical for preserving the exhaust system's longevity in diverse climates. The header-back design allows retention of your original intake manifold while optimizing post-header flow dynamics. This kit includes all necessary components for a complete header-back installation, eliminating piecemeal sourcing.
Built for enthusiasts restoring or modifying 1970–1974 Plymouth Road Runner, Dodge Charger, and Chrysler 300 E-Body models, this exhaust system suits both street driving and moderate performance applications. The X-pipe design promotes even cylinder scavenging across the powerband, improving throttle response and mid-range torque delivery. Buyers seeking a reliable, bolt-on exhaust upgrade that preserves originality while enhancing flow will find this system delivers measurable gains without requiring extensive fabrication or compatibility modifications.
