{"product_id":"flowmaster-flow-fx-extreme-cat-back-exhaust-system-11","title":"Flowmaster Flow FX Extreme Cat-Back Exhaust System","description":"Flowmaster introduces our Flow FX Extreme stainless steel cat-back exhaust system for the 2014-2019 Chevrolet\/GMC Silverado\/Sierra 1500 with the 4.3 or 5.3-liter engine. This system uses a Flow FX series muffler for an aggressive to moderate sound level and increased performance. 3.0-inch mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and durability. The system has a turndown style, dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps improve ground clearance and departure angle when you are driving in more extreme off-road situations. This system produced max dyno gains of 11 hp and 15 lb-ft at the rear wheels.  All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.","brand":"Flowmaster","offers":[{"title":"Default Title","offer_id":51749321703743,"sku":"BDXN_717976","price":369.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/2041\/6831\/files\/717976_1.jpg?v=1769317451","url":"https:\/\/smgspeed.com\/products\/flowmaster-flow-fx-extreme-cat-back-exhaust-system-11","provider":"SMGspeed","version":"1.0","type":"link"}
