Some 4.6L exhaust questions
Do MAC catbacks use a chambered mufflers, because I just heard a clip of them on an 05 and it was one of the sweeter exhausts I have heard. Almost like Flowmaster, but a little better IMO. Also, I have heard not to mix an X pipe with chambered mufflers such as Flowmaster, but I just heard a 5.0L with that set-up and it sounded great!

RE: Some 4.6L exhaust questions
This is what the Mac website says.
Back pressure robs your car of power and economy. Reduced back pressure will cause immediate gains in both power and economy. If you modify your engine, for every 8-10% in power increase you will gain 30% more back pressure which virtually chokes the motor. So any modification at the engine makes a free flowing exhaust and muffler system mandatory. There are three basic factors in noise control: Restriction, Absorption, and Reflection. Restriction is best for reduction of noise, but worst for power and economy (as high as 16lbs of back pressure). Absorption is effective when you pack materials such as fiberglass inside casing, but this is usually quite loud, especially when the packing burns out. Absorption doesn't control reversion. Reflection which is the most effective for power increase is done with baffles and reflector plates with nothing to burn out. MAC Flow Path mufflers use reflection for maximum flow while still maintaining noise control. Instead of a single flow path, MAC Flow Path mufflers use two flow paths for twice the flow and reflection area, while remaining a true anti-reversion muffler. This is what makes Flow Path mufflers the Best Choice! MAC Flow Path mufflers.

Ok, that makes sense, because like I stated, it was similar to my Flowmasters, throaty, but maybe a tad bit higher pitch. Love the sound. Anyone have any clips of their Stang with an X pipe and chambered mufflers??
