header problems Options

[TannerEsser]

i was wondering if there is a way to run a header on a 5sfe with the cat under the header. is there a way to bypass the o2 sensors without driving around with the check engine light on?

Have a bung welded in above the 4 wire and put your 1 wire sniffer in. What year is your Celica? Looks the same as my 94 OBDI California emissions.

Just realized you have a two wire upstream, so you're OBDII.

If you want to run a cat, have a universal Magnaflow one welded in down below and extend the wires to it.

yes he is OBDII, but there were two sensors on my '95 cali spec.

as for that camry manifold, it maybe farther up on it, but i don't understand why you're replacing a stock exhaust with a stock exhaust...
just the a header off ebay! depending where you get it from, it shouldn't be too much
