American Thunder Cat Back Exhaust System
Flowmaster's American Thunder cat-back dual exhaust system for the 2019 Silverado/Sierra 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 with factory dual exhaust. Features include a mandrel-bent 3.50-inch stainless steel inlet tube flowing into a single 50 Series HD muffler, dual 2.50-inch mandrel-bent stainless tailpipes replacing the factory resonators and giving your truck some growl. The tailpipes are finished off with quad 4.00-inch black ceramic coated stainless steel tips that exit in place of the factory bolt-on trim 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" and 157" wheelbases with 6.2L and Factory Dual Exhaust.
