This cat-back American Thunder exhaust system is specifically designed for all 1998-2002 Chevrolet Camaro/Pontiac Firebirds with the 3.8L engine and delivers a moderately aggressive exterior sound with a moderate interior tone. The exhaust system is constructed with 2.50-inch mandrel-bent aluminized steel tubing, includes a specially tuned resonator to help keep the interior tone down to a minimum, then flows into the 80 Series cross-flow performance muffler for a deep muscular tone. The dual 2.50-inch tailpipes split for a true dual exhaust look out the back under the rear valance and are finished off with large 3.00-inch polished 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, hardware and includes our 3-year Limited Warranty.
