In case anyone is interested in what stainless steel Kooks headers and a custom 2 1/2" dual stainless steel mandrel bent exhaust system with spun metallic cats, a 14386 Magnaflow X-Pipe resonator, and 14211 Magnaflow mufflers sounds like.
I did the same setup 2 years ago. Sounds the same today. I love it and get compliments all the time. One of my old neighbors used to come listen to it whenever I was working on it. Said it sounded just like his SS396 Imapala back in 65'.
