Roush Exhaust

Roush has an off road exhaust system and a legal exhaust system. I know that the off road is louder but what makes it louder? Is it just the muffler or something else?

The off road muffler is 10" long and the street legal muffler is 20" long.The street legal kit also has resonated exhaust tips.

I have the legal kit and I want something louder. I was thinking about swapping the muffler with a flowmaster super 44, but should i just get a whole new set up

I went with a Magnaflow, 4"turbo back. Fit was perfect, it came with a flow through muffler but without it there's not much sound difference.
