Show original supplier description
The Flowmaster Universal Dual Exhaust System Kit provides the necessary components to construct a custom dual exhaust system for a wide range of automotive projects. This 16-piece kit is constructed from durable 16-gauge aluminized steel tubing, featuring a silver aluminized finish for corrosion resistance and a clean appearance. The tubing is mandrel-bent to ensure optimal flow and strength throughout the system, with multiple bend configurations included to facilitate custom installations. The kit includes front adapter pipes, intermediate pipes, an H-pipe, and over-the-axle pipes. It utilizes slip-fit connectors for straightforward assembly, though some adaptation and custom fitting are necessary due to its universal nature. Minor modifications may be required, but specialized tools or complex procedures are typically not needed for installation. It is important to note that this is a universal kit and is not a direct bolt-on replacement; some adaptation is required for proper fitment. The kit does not include hangers, clamps, mufflers, or exhaust tips, which must be purchased separately. The main piping diameter is 3.00 inches, and the tailpipe outlet outside diameter is also 3.00 inches, with dual out rear and dual out side exit style options available.
