Not to hijack, but how about with a stock 1 7/8" exhaust?
Just got my 75 Dart and it needs a muffler but I am not financially able to spring for an upgraded exhaust just yet.
I have a 74 duster with the slant six that will eventually get swapped for a small block but for the time being I want exhaust, but nothing that will sound tinny or weak with my current motor. Any suggestions?
