GMC Sierra 1500 Performance Exhaust - Flowmaster - FlowFX Cat-Back - Black - 09-13. Built for 2009-2013 5.3L trucks, this cat-back adds a deep, assertive tone with straight-through flow and dependable construction.

Made from durable 409 stainless steel, the system runs a 3.00-inch inlet into a single-in/dual-out Flow FX straight-through muffler, then splits to dual 2.50-inch mandrel-bent tails. Angled side exits behind the rear wheels help route exhaust away from your boat or trailer when towing. Finished with twin 4.50-inch black ceramic-coated 304 stainless tips, it reuses factory hangers and adds a left-side hanger for a secure fit. Includes hardware, detailed instructions, and clears the factory spare. Fits 2WD/4WD with 143.5- and 157.5-inch wheelbases. Sound is aggressive to moderate. Limited lifetime warranty.
