Flows sound good, but oyu might as well put concrete to block your exhaust flow in the pipes..Ever seen inside one? My 22" sounded stock when I first installed it, but it got louder over time. I actually am in love with my exhaust (JBA catback and 22" Mag)...I have heard Banks, Nismo, Flows and Dynomax in person on Titans (lots of local members), but to me, I would take my Mag exhaust over anyone of them. I did however want to try Borla, and I may one day. But all the rest can stay home IMO....Oh, and I get complimented on the exhaust a lot with the Mag, but then again, I have no cats at all, so mine is deep and aggressive sounding...Good sound is just in the ear of the beholder....Also wanted to add, in case people think I am just a big Mag fan. Before this truck, I never owned a Magnaflow muffler, this is the first I have ever owned, however, it was made me fall back in love with my exhaust...Now to give Borla a try
