I would like to buy from the catalytic converter back to the muffler tips for my 1986 coupe with 4+3 trans.
I prefer mufflers that will not "drone" at highway speeds. If you have square tips and/or polished tips that would be plus.

I gave up on anything good, used and bought new for $229.00 + $40.00 shipping. I expect them to be quiet like OEM.
