While it’s impossible to say which system for Silverado 1500 will sound best to you, most buyers are happiest with exhaust kits that produce a deep and rumbling roar of a sound. This is achieved by kits such as the Flowmaster Super 44 that uses wide pipes and a carefully optimized muffler for a sporty sound. Each kit sounds different though, and it’s up to you to decide which cat back exhaust system is the one you want for your ride.
