Constructed from 2.50-inch mandrel-bent stainless steel, this system offers maximum performance and durability. It features a built-in H-pipe that produces a mellow, smooth tone while eliminating back rap during deceleration. The inclusion of Super 40 Series performance mufflers provides a deep exterior sound with a moderate interior tone. Dual tailpipes are tucked high for clearance and exit straight out the back under the rear bumper, ensuring a clean fit. Like all Flowmaster systems, it enhances throttle response, power, and fuel efficiency, making it a performance-oriented upgrade. The system is designed for easy installation, including all necessary hardware, and is covered by a Lifetime Limited Warranty.
This exhaust system is specifically tailored for 1955-1957 Chevy models with a classic V8 engine, fitting both coupes and sedans. It does not fit wagons or convertibles.
