Dang, Dean, you're always a few steps ahead of me. Though not original, I will have to replace the dual exhaust in my 71 K20 when I get there. The previous one was "aluminized" and didn't last as long as I thought it should.
What kind of mufflers are you running? Is it quiet or have a bit of rumble to it? How did you buys bend your own tubing? I gather you may have needed some special equipment not to mention the welding. And, finally, about how much did it cost? just planning ahead. Thanks.
P.S. What, No A/C?
