Its time for some new mufflers on my 66. I currently have 2.5" exhaust with an x-pipe and original 2 chamber flowmasters. I am looking at borla pro-xs, magnaflow, and 3 chamber flowmaster delta-flow mufflers. If you have any sound clips of these mufflers, please post them. I've already looked at the mustangexhaust.com website, but wasn't able to find many clips of the borlas.
