Thanks for the reply guys! Just got back from the shop and saw the condition of the tube and muffler. It looks like my muffler exploded - full of cat mat. The tubes from the dpfe sensor were still on, but the upper metal tube connector on the egr tube was cracked - hense the hissing. No heat from the vents - water pump time. Metal impeller pump being replaced in two days. New thermostat, colant flush, and pcv valve at the same time. Also Just ordered a 2" stainless magnaflow from CT - 20% off. For the time being my ride is a 2004 accent gsi - girlfriends car.
Roger - point taken on the sig - I'll change it soon. 95 se 2.5 mtx.
