I would like a nice throaty sound, without too much noise under normal driving for my 1980 911sc 3.0L Wide open it can be quite loud and fun.

Nothing beats Dansk for best power without annoying drone.
I have the stainless steel pre-muffler (replaces the cat) and SS sport muffler with the single 84 mm outlet. Great performance, great sound and lower oil temps...a Trifecta!

iFox,
I think you are correct...no cat on the '78 911SC. SSI's will improve both performance and sound on the SC's. You will not lose heat. You will need a new muffler with two inlet connections. You will not be disappointed with the improved performance.![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
I had SSI's on my '77 911S ROW and loved them. They connected to a Dansk 2-in, 1-out sport muffler. Really made a positive improvement in performance and enjoyment.
