3" round vs 3.5" oval ??
Trying to decide what to do with my exhaust. Years ago I came a cross a Winston Cup road course exhaust system. Has a nice Dr. Gas x-pipe setup. Yes I said Winston Cup so you know how long ago that was ... LOL . Ok FINALLY getting close to start thinking about exhaust for my 67 'Bird. The area cross section between the two isn't that different.
The area of a 3" circle is 28.274333882308
The area of a 3.5" oval is 31.415926535898
So I'm wondering is it worth adapting the 3" collectors to this setup or just go with a more conventional 3" x-pipe system???
