hookers

seriously, when it comes right down to serious racing Hooker Super Comps are pretty much the best you can get. Hedman's Torque Step headers are supposed to be pretty good too - but Hookers FTW

all these bbk people i dont get. they've been around for about 20 years, while hooker has been designing headers forever and a day

BBK makes a good quality header for the price. That is why...

Plus you save $3-400 with some of their headers.

I am comparing ceramic to ceramic coating.

Hookers are a bit better. I just do not like how they point upwards at the end of the collector.

as long as you have O2 sensors installed in the collectors they should pass jsut fine.

and the tip of the collectors point up for ground clearance. if you have to whack the bottom of your floor pan with a ball peen for clearance big whoop [8D]

most wont carry a CARB #. and they're not really legal since they change where the cats are placed. legally you're not 'posed to move the cats
