Due to the high temps, expansion and contraction, leaks of varying extent are common on all of those connections and will potentially cause your car to fail emissions testing - particularly low speed NOx. All four of our c900t's had them. Suggest you remove the elbow, turbo side cover, downpipe flange and turbo/manifold bolts. Clean all surfaces, check the metal gasket for burn-through and reassemble with high temp exhaust sealant putty (not silicone-based gasket goo.) Replace any suspect bolts, studs and nuts with new. About a 2-3 hour job and a good time to replace the O2 sensor as well.
