This Flowmaster American Thunder® cat-back dual exhaust system for the 2019-2023 Silverado/Sierra 1500 (new body style) trucks with the 6.2L engine is perfect for the person looking for an aggressive sound level outside the truck, with a moderate interior tone and all the performance benefits you would expect from Flowmaster®. This emissions-legal bolt-on system fits all 6.2L Crew Cab with 5.5-ft and 6.5-ft beds, and all Double Cab with a 6.5-ft bed and factory dual exhaust tailpipes. Features include a mandrel-bent 3.50 in. stainless steel inlet tube flowing into a single 50 Series HD™ muffler, dual 2.50 in. mandrel-bent stainless tailpipes replacing the factory resonators and giving your truck some growl. The tailpipes are finished off with quad 4.00 in. black ceramic coated stainless steel tips that exit in place of the factory bolt-on exhaust bezels giving your truck an aggressive performance style and setting your truck apart from others, sending the message that you would rather lead than follow. Designed for an easy fit, this system includes all necessary parts, detailed instructions and hardware for an easy at home installation. Notes: Fits 147 in. and 157 in. wheelbases with 6.2L engine and factory dual tailpipes.
