{"product_id":"flowmaster-american-thunder-cat-back-exhaust-system-78","title":"Flowmaster American Thunder Cat-back Exhaust System","description":"Our American Thunder cat-back exhaust system for 2007-2013 GM Silverado\/Sierra 1500 with the 5.3L engine, is perfect for the person looking for moderately aggressive sound levels both inside and outside of the truck. This bolt-on emissions-legal system features 3.00-inch mandrel-bent stainless steel tubing flowing into a Super 40 Series muffler, for a deep powerful sound. The mandrel-bent 2.50-inch stainless steel tailpipes can be configured with your choice of exit locations, either straight out the back under the bumper for a muscular look, or exiting out behind the rear tires on each side of the truck. This is the ideal tailpipe location when towing a boat or RV. The tailpipes are finished off with large 3.50-inch double wall polished stainless steel tips. The system includes all necessary parts and hardware for an easy installation and is covered by our Lifetime Limited Warranty. Notes: Fits all 2\/4 wheel drives with 143.5 and 157.5-inch wheelbases. Also fits 2007-2008 GM Silverado\/Sierra 1500 with 4.8L engines and 143.5 and 157.5-inch wheelbases.","brand":"Flowmaster","offers":[{"title":"Default Title","offer_id":51749435932991,"sku":"BDXN_817680","price":1177.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/2041\/6831\/files\/817680.jpg?v=1769321456","url":"https:\/\/smgspeed.com\/products\/flowmaster-american-thunder-cat-back-exhaust-system-78","provider":"SMGspeed","version":"1.0","type":"link"}
