I've been reading a lot more and wow, didn't know there was so much to understand about headers, collectors, size of H pipe and relationship between torque and the sizes of pipes.

Apparently, people with OBX are very happy with fit, finish, performance and lingevity. Haven't found anything bad about them but these are folks who generally want to put a set of headers on and call it a day. For supercharging though, it looks unavoidable that I'm back into the premium stuff.

I read lots of positive reviews about Kooks, so so reviews about LG and nothing but things about American Racing. AR is the only one who charges for O2 sensor extension harnesses ($100+) but if you're already into $2200 headers, what's another C note I guess. Still researching though so I'm going to check out Borla and Pfadt's "Tri-Y" idead.
