Description
This high performance muffler has been developed for vehicles with 4 inch sidepipes such as 1965–74 Corvettes or vehicles equipped with Hooker super competition roadster and side mount headers. These mufflers produce an average of 23 percent more power than open Headers and feature a high–flow, perforated core that operates at 99 percent efficiency. High temperature packing material absorbs noise while producing a powerful mellow sound. These mufflers, as tested on a 1968 Corvette with a 427 cu inch engine increased horsepower by 40 at a peak of 5500 RPM and 20 foot pounds at peak of 4500RPM versus a leading aftermarket undercar header and turbo–style muffler combination. The outer case is constructed of durable 16 gauge aluminized steel protected by electrostatically applied high–temperature black paint. The inlet/outlet is a 2.5 perforated core in a 4 inch casing.
