We have 2 cats the precat is on the manifold then the main is after it
if you get a header you'll need to use a "non fouler" on the first o2 sensor so you don't throw a cel
It's the 2nd o2 sensor
injen and aem are the ones many of the proteges use for intakes...never had a a header
how about this free airmod with the current intake system? http://www.clubprotege.com/forum/printthread.php?t=1977&pp=100&page=1
Also check out Tamn's build thread above. Lots of ideas on lightening up stuff for bunch more mpg. Just not sure how your wife would feel about some of them but do check it out..............Very interested, PM on it's way
