Where is a great place to buy a t3 turbo downpipe for a D16 engine in a 92-95 civic? I keep trying to find a place but no luck.

 

make it yourself. order from jegs or summit whoever, order some 2.5 inch piping, here is how i ran mine, i had..
i order 1 180 degree bends, 3 120 degree bends, 1 90 degree and about 3 ft. in straight. also about 1 1/2 feet of 2.5 inch cooling hose (from local carquest) and some size 40 clamps.
not too difficult to do.
