i have decided that i will use 2 1/4" from the manifolds to the muffler. Now if i ran 2" from the mufflers back would it still have that old tractor sound. would that hurt the flow. would i be better off to run 2 1/4 straight out the back? my tail pipe hangers are 2" and i would like to use the original style but not if it will hurt the flow. Rod.
