Magnaflow vs. Flowmaster - Which Exhaust System Sounds the Best. I have a 2009 Silverado 5.3 with the stock exhaust. It seems like it has gotten louder as it's gotten older (3.5 years) but I like it. The exhaust is one of your vehicle's key systems when considering overall performance. Two of the most popular manufacturers are Magnaflow and Flowmaster.
