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 system is constructed from mandrel-bent 2.50 in. aluminized steel flowing into a specially designed Super 40™ Series muffler for a moderately aggressive exterior tone and a moderate interior tone. The system finishes with dual 2.50 in. tailpipes and polished 3.00 in. stainless steel tips, and your choice of tailpipe exits either straight out the back for a muscular look, or exiting behind the rear wheels which is ideal for towing. The system uses the factory hanger locations for an easy installation and is covered by our 3-year Limited Warranty. 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 easy installation. Comes with our 3-year Limited Warranty. For those who prefer full stainless steel construction and a Lifetime Limited Warranty, check out exhaust system part# 817473.
