Recently I was browsing through a couple of posts on here when I came across someone saying that their was an exhaust called MBPR (I think thats right). This exhaust interested me because people have said that it was one of the most throatiest but loudest exhaust systems out there for the focus. I like the throatiest part but not quite sure about the loud part b/c of police issues. Well upon browsing modernperformance.com, I came across some Stainless Steel Resonators and I was wondering that if I used those resonators when if i bought the exhaust how much of a difference in loudness will it decrease??
