hey, i recently blew my kat
. i bought a 91 240sx and is going to use it as a donor. i was wondering how the exhaust set up is going to work? i want to get my car back to stock so i can pass smog. should i use the s13 exhaust mani with the egr tube? or buy a stock s14 exhaust mani? i noticed there is a extra O2 sensor on the down pipe (bottem portion of exhaust mani) in the oem s14 exhaust. dont i need that? wouldnt i get a CEL? or fail smog? i have a downpipe from my turbo set up, couldnt i buy a s14 mani (top portion) and weld a bung onto the down pipe? and connect those two together?
