Exhaust set up idea

I ran a set like that behind my 440 GTX for years (in my younger days..). It is very loud, quite a bit of vibration to the floor pan too, but at WOT...nothing like it!!

If you do go this route I would relay one suggestion that I learned the hard way. Make sure to anchor the mufflers with their own supports as the weight over time created leaks and too much stress on your headers. I was just too young and cheap at the time...
