Which flowmaster exahust system would best fit my truck i have a 1999 ford ranger?

From my understanding with flowmaster, the number is what determines it, for instance let's say a flowmaster 44 vs a flowmaster 10, the 44 will be quieter, but have a deeper growl, more low pitched. The engine will be the biggest factor, whether it's the 4 cylinder or 6 cylinder. It's not a v8 so don't expect that v8 growl. It will be more of a hum than growl. For louder, go for a low number like a flowmaster 10. Quieter but deeper, go for a flowmaster 40 or 44, and so on
