The crap constantly all over the rear bar would be a pain..
The link I posted to the youtube video sounded alright to me. But each to their own.
I was more doing it for looks than sound. I wouldn't want it to loud and droney but a nice note would be alright under acceleration.
The other option would be a mock tip. Just remove the cover and weld it straight to the standard muffler keeping everything still in place. Pointless and hardly worth the effort though haha.
I had a 65 mustang and diff dumped the pipes but built a bracket to still hold the tips and a section of the exhaust so it still looked standard.. Kinda the same thing
