Finish off your HEMI Swap project with the finest exhaust system available for your 1970-1974 Dodge Challenger & Plymouth Barracuda (Mopar E-Body). Features 3" diameter, straight through 304 stainless steel, zero restriction mufflers, and 304 stainless steel mandrel bent exhaust tubing. Specifically designed for HEMI swap vehicles and a direct fit to BH2358 Long Tube Headers. Slip couplers allow the first 24" of the head pipes to be dropped in seconds, allowing the transmission to be easily removed for service. High tuck design for best possible ground clearance for lowered cars. Additional exhaust systems will be released for the E-body at a later date.
