I have a 69 B Body that I am going to put a set of 3.5" round styly mufflers on, not interested in Borla or Flowmaster or Dynomax......I was wondering if anyone has had a local or custome muffler made they were happy with.

I'm not looking for it to be quiet, I need it to be durable, and very minimum restriction....say 16" long up to maybe 20 " long ????
