I have a 1957 Chevy NAPCO truck with a 283. I researching exhaust options. Has anyone ever tried the universal dual exhaust kits for the piping? As an example: http://www.speedwaymotors.com/Mild-Steel-Exhaust-Bend-Kit-2-1-2-Inch,36340.html
They seem cost effective, and in my case might mitigate my concerns regarding clearances around the transfer case. Also, I believe they are mandrel blends. Thanks.
