I have just gotten my 71 911T Targa back from the welder, so much of the brown biscuit is now turned into steel:-). When starting up the cabin filled with very blue exhaust (had been standing for over a year), which gradually turned less blue. I am obviously getting exhaust from the heat exchangers into the cabin so I am afraid that the exchanger has rotted. My plan is therefore to install a set of SSI headers:

While I am at it I would like to change the muffler too. I have a complete stainless steel sport system (incl muffler) from Dansk on a ´77 911S and while I love the sound I am a little afraid it might be too loud on the Targa which mostly will be used topless (the car - not me).
Does anyone have experience (or better sound comparison:-)) with the steel sport muffler from Dansk vs their stainless steel version?
