Mac Pro Dumps

Macs vs Flows?

Would you guys say that the dumped macs are louder than dumped flows? I've got 40 series w/ 2.5 inch turndowns and they're pretty loud. :shrug:

Mytight do you get a vibration at low rpms??I took a spin in 50_GT_kid car once and he had a extrememly bad vib through out the entire car up until 1,900 rpms then it would clear. This was with flows dumped.
Mabey that kids exhaust was hitting the floorboards
 
my o/r H pipe w/ macs n tails give my dash and accessories a bad vibe at about 1800...(= annoying) plus any change in my console compartment would rattle at various rpm's, without anything touching the frame or floorboards, its just the drone and sound that does it to me. my experience from other cars is that dumping mufflers makes the drone louder, and the interior noise MUCH louder
