Nothing and I mean NOTHING sounds like a 5.0. I can be out with friends and hear some fire up a 5.0 in a parking lot and I stop and look around. Most of my friends have have a WTF look on their face. I just point out the 5.0 and they understand then.
the 5.0 is one of the greatest soundings engines.....I dont care who you are.... I originally was a 4.6L guy a long long time ago so my opinion is not too biased
5.0s sound good, 4.6s sound a lot better... 03-04 Cobras with Long Tubes, OR X, and Borla Stingers/SLP LM 1s/Bassani sound stupid good! I might be going with a stinger catback on my car in the next year or so if I do what I want!
the best i have ever heard is my dads 70 boss 302...solid lifters, a huge cam, longtubes, h-pipe into 2chamber flows. absolutely wicked. the next best would be my buddys neighbors terminator....i dont know what exhaust but i do know its got a kenne bell at 19lbs and some kind of custom ground cams
