Vette(s): 1980 L-48 still in the middle of a frame-off.
I have a 1980 corvette with true dual exhaust, no cats and the KBDs.
I think they sound great. Just a tad loud but that's OK. Only one problem that I have had is rust.
The black paint on them is just a finish paint and not worth beans. I painted the mufflers with a high temp paint inside and out and this helps a lot. You need to keep an eye on the chrome tips. they need to be kept clean of rust too.
The sound is a deep growl at idle and seems smooth at speed. I have a video on youtube, search for kbd corvette muffler sound. I have a crappy camera but you get the point.
I give it an 8-9 for sound and performance, a 5 for finish since I had to paint them.
Corvettes and women are the same...You want to make love to them but they keep breaking down.
