For the person who wants a subtle custom appearance with all the benefits that a Flowmaster Cat-back exhaust system provides. This American Thunder system for the 2001-2006 (2007 Classic) Chevrolet Silverado, GMC Sierra 2500HD/3500HD with 6.0L or 8.1L engine with dual inlet muffler, delivers a moderate interior tone with a deep powerful exterior tone and is suited to the enthusiast who wants their performance to be heard. The system attaches to the back of the catalytic converter with a dual inlet 50 Series Big Block muffler for a deep powerful sound without being obnoxious. Includes a large custom formed aluminum heat shield with stainless clamps and easily attaches directly to the muffler body. The custom bent 3.50-inch 409 stainless steel tailpipe uses the factory hanger locations for an easy installation and exits out behind the right side rear wheel which is ideal for towing. The tailpipe is finished off with a large 4.00-inch polished 304 stainless steel tip embossed with the Flowmaster logo. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts, hardware and easy to follow instructions for a trouble free installation. Covered by Flowmaster's Lifetime Limited Warranty.
