Hooker Aerochamber Mufflers on a 408 68 Dart

I have them on my 525hp 426 wedge, and they are loud as hell, lol dumps at the axle as well. TTI headers and 3" TTI Xpipe system. They quieten down once you get rolling, i have a .245/.251 duration solid lifter cam at .050, so it a bit lumpy. Had them on my BBC Camaro as well. I like the sound.
