The American Thunder® system is heavy 16-gauge mandrel-bent aluminized steel tubing for durability and maximum performance. Includes a stainless steel Super 40„¢ Series performance muffler for that perfect blend of a deep aggressive exterior sound, with a moderate interior tone that won't drive you out of the cab when having a conversation. The dual 2.50-inch tailpipes clear the factory spare tire and give you two choices of exit locations. Straight out the back for that true dual look, or exiting out each side behind the rear wheels, which is ideal for towing. The system is finished off with a pair of highly polished 304 stainless steel tips embossed with the Flowmaster name. Designed for an easy fit, these systems include all necessary parts, hardware and instructions for an easy installation you can do at home. Covered by our 3-year Limited Warranty. For those who prefer all stainless steel construction with a Lifetime Limited Warranty, check out exhaust system #817428. Notes: Fits 2\/4 wheel drive with extended cab\/short bed with 143.5-inch wheelbase.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eIncludes Hangers and Hardware for an Easy Installation\u003c\/li\u003e\n\u003cli\u003eMandrel-bent 16-gauge Aluminized Steel Tubing\u003c\/li\u003e\n\u003cli\u003eModerate to Aggressive Exterior Exhaust Tone\u003c\/li\u003e\n\u003cli\u003eConnects After Factory Catalytic Converter\u003c\/li\u003e\n\u003cli\u003eDyno-tuned for Maximum Performance\u003c\/li\u003e\n\u003cli\u003eSuper 40 Series Performance Muffler\u003c\/li\u003e\n\u003cli\u003eUses the Factory Hanger Locations\u003c\/li\u003e\n\u003cli\u003e3-Year Limited Warranty\u003c\/li\u003e\n\u003cli\u003eEasy Installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eRedline360 is an authorized Flowmaster dealer and sells only genuine Flowmaster products\u003c\/em\u003e.\u003c\/p\u003e","brand":"Flowmaster","offers":[{"title":"Default Title","offer_id":40352505397328,"sku":"17428","price":849.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0058\/0252\/4785\/files\/817428_974d35ba-7af1-4a97-a542-141de34f25c4.jpg?v=1751312289","url":"https:\/\/shop.redline360.com\/products\/flowmaster-exhaust-chevy-silverado-gmc-sierra-1500-4-3l-4-8l-5-3l-99-07-2-50-catback-american-thunder-17428","provider":"Redline360","version":"1.0","type":"link"}
