My car isn't an early one (vin# 6938) but when I turbocharged it with a single turbo about 40,000 miles back I installed a glass pack muffler which is considerably smaller in diameter than the stock Walker muffler. I removed the heat sheild at that time and have had no ill effects. Admittedly, the smaller muffler dissipates the heat further from the engine than the stock muffler.
