The Way the 3v 4.6L should sound!
Currently have a JEGs off-road H pipe, originally had SLPs which were WAY too loud. Switched to: http://www.americanmuscle.com/flowmaster-ss-axleback-0510gt.html which was far more streetable and sounded very good. This year I wanted something new. Installed the MACs yesterday. For sound level, about the same as the Flowmaster 60s. BUT for sound quality the MACs certainly have the more favorable "muscle sound." Barely any "3v buzz" and no infamous trumpeting. It is all a very deep/aggressive pulsing and burgling exhaust note. The only pain was the fitment, not quite a flush fit. There is a drone but not terrible. Very happy. 4 stars for overall satisfaction for sound quality and some issues during install.
