OldBlueTruck I have a single 22 inch Smitty on my 62 1/2 ton 235 c.i. truck and it is very quiet!! I would like to have a little more 'Rumble" without too much noise but haven't been able to find that combination with a single exhaust. Any one have a suggestion?? I did have a very good sound once when an old original muffler burned out inside but haven't had that sound since...
