Mandrel-bent 16-gauge Aluminized Steel Tubing. Material: Aluminized Steel. For the person who wants the aggressive look of a NASCAR race truck along with all the benefits that a Flowmaster Cat-back exhaust system provides.
Had trouble fitting the muffler to the dual outlets. The clamps are garbage but overall a nice product. The nipple placement for the rubber holders is nowhere close to where they should be. Plus side is the quality of galvanized is good and the welds look perfect.
