Does anyone know whick of these brands are better? I don't want the drone of flowmaster but I still want a high flow system. I know I got to give a little with the in cab drone. I used to have a 5.0 mustang and liked JBA then, but do they make good truck parts. I heard of MAC but thats all nothing negative nothing positive. So maybe y'all that have been around the truck scene longer will know better than me

 

I have a Flowmaster cat back on my 04 FX4 and there is virtually no cab drone at cruising speed. The kit came with a 50 series muffler. 40's are where the cab drone comes from.

 

I know there are a few that would swear up and down over their Bassani, Borla and Banks systems too. I had a similar thread started up a few months back.....I can't recall how big it turned out being (pages) but you may wanna run a search.
But it would be interesting to see how things may have changed over who likes what and for what reason...

Happy system hunting...
