Can a Flowmaster 44 Muffler work on a 2003 Ford ranger V6 3.0 Engine?

I have been wanting to put a loud exhaust on my truck for a while now and i took it to a local muffler shop and they recommended i use another muffler because the Flowmaster super 44 won't work well on my truck. But i have seen some youtube videos that show other results should i use the Flowmaster super 44 Muffler?

It depends.

Some people say Magnaflow is less restrictive and gives more power, but Flowmaster may sound better.
