Default O2 sensor question

i've got a d16y7 in my '00 dx & i'm gonna get a DC sports 4-2-1 header w/ high flow cat. on the y7 EM there are 2 o2 sensors, one before the cat, & one afetr. on my header & cat, there is an o2 sensor on the header, & one on the cat. do i have to put the stock o2 sensors in the same order or will it matter?

Absolutely!

And you may wanna consider an O2 simulator for the "after cat" sensor. You will get a CEL from the header. The O2 sim will clear that up.

depends if the "high flow" cat is an actual cat. some high flow cats are just straight pipes. if it's a real cat, put the sensors in the same order. if it's a straight pipe, you'll need an O2 simulator for the second sensor. and you'll need to lengthen the second O2 sensor for the cat because i believe on the d16y7, the cat is on the header before the downpipe, and on the new headers and cats, the cat comes after the downpipe. that's what i experienced with my d16y7 99 lx...
