Description

For the person who is looking for a complete Crossmember-Back dual exhaust system with a moderately aggressive tone for their 1964 to 1972 Chevrolet/GMC El Camino/Sprint with a V8 engine. With easy fit in mind, these systems are constructed from 2.50-inch mandrel-bent aluminized steel with a built in H-pipe to equalized the exhaust pressures, eliminates backrap on deceleration and makes maximum power. The system includes a pair of specially selected Super 50 Series mufflers for a deep powerful exterior sound with minimal interior tone and is suited for the enthusiast who wants their performance to be heard, just not inside the cab. The mandrel-bent tailpipes exit at an angle behind the rear wheels and are finished off with large 3.00-inch angle cut polished stainless tips for an aggressive look. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation.
