Acctually i was at the ferrari races at watkins glen last year...friend of mine's dad is a salesman for it so we got to hang in the pitstjm73 said:You haven't heard an exotic car sound until you hear a Ferrrari V12 with the factory hi-po exhaust upgrade racing around the road course.It's like sex for the ears. It changes you.
Now mac to the question at hand. The MAC muffler burble and drone on my '90, so I'm sure they do the same on the 4.6 too.
Does anyone have the Delta Flow 50 Flowmasters? They claim less resonance (drone) and I've never heard if that's BS or true.

its funny you say that because i was just having this convo with Joe at Mustang Magic (the best mustang shop out here in Long Island) He was telling me the same thing that pro-chambers make a much better sound and actually has made more power with a Mac setup on his cars than any other X or H, cats or not. As for mac, he said that he has done tests on all the exhausts he sells and mac makes the most power hands down (acording to him, on a modular engine, flowmaster cat-backs actualy lost 2hp) he is a dealer of bassani, magnaflow, all those money out the wing-yang "top-end" exhaust and yet he uses mac on all his mustangs, his 88 LX, his 99GT, his 03 cobra and his new 05.......i think that sais a lot.
