Well I too couldn't find what you are looking for for my 70 challenger that was affordable and not a cherry bomb muffler. You could do what I did, Just put the turndown piece on the outlet of your muffler and run as short a pipe in the front as practical. Of course you allready know that what you loose in weight, you may give up in ET if you have it optimally tuned now. You may be tweaking (the length) it for a while. Single stage flowmasters are used by most in IHRA pure stock so you should be good there.
If you don't need an exhaust at all, look into the header inserts they qualify as "mufflers"
My car picked up MPH and ET with the mufflers......dynomax street legal round 3.5 mated to the 3.5 outlet from the headers.
