Chevy 1500 Exhaust Magnaflow Flowmaster comparison
Magnaflow & Flowmaster Comparison. We have many people ask how these two popular mufflers sound, while it is difficult to describe using terminology that some may not be accustomed to while talking about Exhaust, this video can not even represent the true nature of these sounds. There are many variables in how a vehicle sounds, even on two exact same vehicles, the same setup can sound different. We just hope this video may put some insight in the main differences of these 2 very different mufflers. Both trucks are chevy 1500's with the 5.3 engine. The white truck has a flow master super 44 series muffler, tails coming out the back. It is setup from factory with "2" converters. The black truck has a Magnaflow with a 14" shell. The shorter shell the louder it is when it comes to Magnaflow, as they don't have "Series". Tails are turned down, and it is setup from factory with "3" converters, (which will quieten it down a bit.)
