High flow cat worth it?

I have no secondary cat (one under the cab of my truck) i got a flowmater 40 series and its dumped right after. right now w/o the cat is super loud but sounds mean, would a high flow cat be worth putting on performance wise? and would it quiet it down a bit?

Did you notice that post was from 2009?
In fact I did.

The guy you were asking is banned from the forum, according to the word "banned" under his moniker. So the likelihood that you are going to get a response from a 12 year old post by a banned member is zero. But perhaps someone else with similar experience will see your question and chime in.
