Howies01 Posted July 1, 2006 Report Posted July 1, 2006 I'm going to be buying some drag pipes before very long for a 421 cub with 39 PWKs. What, if anything other than aesthetics, is the difference between the pipes that are both out one side as opposed to one out either side? Only thing I can think of, performance wise, would be maybe the symmetry in the overall length of the pipe from the exhaust, but would the 3 inch difference really amount to anything? Quote
