For the person who wants the look of a traditional dual exhaust system with all the benefits that a Flowmaster® cat-back exhaust system provides. The American Thunder® exhaust systems are the perfect choice for the person wanting a deep powerful tone outside, with a mild to moderate increase of sound inside the cab. The exhaust system features a dual inlet flange that attaches to the factory flange behind the catalytic converters, all mandrel-bent stainless steel tubing flowing into a Scavenger Series Y-pipe for maximum scavenging of exhaust resulting in increased torque. The system then flows into a 70 Series™ "Big Block II" performance muffler giving you a deep powerful tone outside, and mild to moderate interior tone inside the cab. The dual tailpipes can be configured for either dual out the rear under the bumper for a muscular look, or dual out the sides behind the rear wheels, which is ideal for towing applications. The tailpipes are then finished off with a pair of 3.00-inch polished 304 stainless steel tips. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for an easy installation and is covered by our Lifetime Limited Warranty. Note: Fits 2 and 4 wheel drives with the extended cab/shortbed chassis. |
