Header Install

[turdburglar]

ok i epoxyed the eyebrows on and have the header installed on stock exhaust with the first o2 sensor installed. i have to wait until i get the rest of my exhaust work done before i can put the second one in. is this going to harm the car by only having the first o2 sensor on the car other than having the check engine light on? another question. what size manifold/pipe flange gasket is usually required for a header? the stock one for a d16y7 is too small. maybe one for a d16y8? since the d16y8 has somewhat of a stock header.

I dont belive it will harm it but you will probably throw CE codes

[dubcac]

Yep, CEL will be on.

yeah and your gas mileage might go down a little bit

ga mileage went way the fuck down. i was doin a tank a week going to and from work 70 miles per day. now im doin 2 tanks a week. i gotta get that cat and second o2 sensor in there

[NstyGrnHatch]

holy shit! Hi Flow is bendin you over that bad?!?

thats the thing the second o2 sensor and cat arent even on there. all im runnin right now on it is header, precat o2 sensor, stock exhaust piping with resonator and aftermarket muffler. gas mileage is killin my bank

ok i have semi-solved my problem with the gas mileage. still havent got the exhaust finished. i have a question though. can i splice the second o2 sensor wires into the primary o2 sensor wires? will the car run ok? or would that just be pointless and fry my ecu?
