Congrats on a great car. my advice is ... keep it stock.

I am a stock purist myself but perform "period upgrades".
I was convinced to replace the old original WG spring since I could get no more than 0.6BAR
I exchanged it with a 0.9 RUF spring and replaced O-rings on the presure side. There was a huge difference.
The original cams tend to fade out on high revs and i have excanged them with SC cams in cooperation with Euro exhaust. It now push hard beyond 6000, but the turbo also have its limits in its range.

Regarding muffler, the 930 was single outlet until 1984 as far as i remember..... Anyway my 78 is single outlet.

Hav fun
