My 1977 911S came with thermal reactors which I took off the first time they warped, and replaced with headers. Since then I have replaced the headers and heat exchangers with SSI heat exchangers from the Tweeks catalog. Now (years later) the muffler has begun to vibrate and rattle, spoiling one of the things I enjoy most about the car - it's sound. I was told that the original muffler that came with the reactor-equipped 911s was made with less baffling and backpressure because of having to go through the reactors. I would like to replace the muffler but not compromise the wonderful rich sound it produces.

My thoughts are to ask those on the list who may have gone through this already for advice. If one of you has an original muffler like mine that you would wish to sell, that would be a good way of keeping the sound I have come to enjoy, or if you have replaced yours and can help steer me to an aftermarket muffler that sounds great, that would be appreciated too. Thanks in advance.
