I been thinking about dualing my exhaust on my 07 Mustang, Im not sure how well the 4.0 will sound. Found some bolt on shorty headers, plan on using th X pipe and running true duals. What mufflers sound good on the 6? Maybe some Magnaflows?
These 4.0's don't sound that bad at all when opened up some. Here's a vid I made to show how it sounds with dual exhaust, no axle backs and with SLP Loudmouths (basically straight pipes). I'm currently back to the GT takeoffs & bassani x pipe because of the low back pressure the SLP's caused and they're a little droney for every day city driving. The GT takeoffs are a bit too quite, but I think if you stuck with any sort of muffler like maganaflow and what not, you'd be right on the money.
