      Nice product, but read on...

      I bought a set of these awhile back and installed. The easiest way is to disconnect battery (VERY important), removed strut tower brace, remove motor mount bolts, and lift the engine slightly from underneath. Next, you may find it easier to pull the RH engine mount bracket for clearance and a swivel-head gear-wrench works wonders on header nuts. GREAT fit, but would not stay in closed loop (o2 sensors up front) being they're not ceramic coated. Thin SS needs coating for DD cars or they cool too fast and try to foul plugs. Thick aluminum LTs will do the trick as well. o2 sensor heat circuits could not be turned on long enough to compensate by my local tuner (and a well-trusted one), so for now I'm back to stock until I send for coating. The o2 sensor bungs from stock manifold to these LTs move back over a foot! Thought everyone should know this BEFORE the pain that I went though happened. Car runs fine for now. F/I and heavily modified cars likely wouldn't see this issue, I'd suppose. A lot of work to pull them back off so I can drive without issue...
