I have the LCE header on my truck. Mine is not ceramic coated, though, it's stainless steel header. As has been pointed out there are two schools of thought on headers for the R motors, tri-Y or 4-to-1. The LCE is 4-to-1, the Thorley and NWOR use a tri-Y. The claim is that the Thorley does better at the low end of the RPM band, while the 4-to-1 doesn't start to show improvement until your engine gets up in the revs a bit. Well, no R motor is going to have much torque below 1500 RPM, so a small bump does there isn't going to matter. You need to get the little motor up into the RPMs to produce any power, so you really should optimize for 2000 to 4500. Anyway, happy enough with mine. I would skip their exhaust (I have LCE from head to tailpipe), it's too loud IMHO. But I paid around $700 for a complete stainless exhaust system, which is made well.
