Longtube Headers

Ticket-Me-Yellow · February 4th, 2008, 01:50 AM

Alright so i was talkin to the emissions dude the other day and he said as long as your check engine light isnt on ur basically fine. So does longtube headers set off the check engine light?

you can do a few things to over ride the system... you can turn off your rear O2 sensors but if they plug in they might be able to tell... you need to ask him to what extent the computer checks

yea cause i really wanna throw some long tube headers in my car but as it looks right now i cant because i live in illinois and we have emissions.

well if all they do is plug in and check to make sure that its getting a reading you might be able to MIL it and get away with it... if you turn off the rear O2's that might trip there system and fail you

whens your emissions due? mine just expired, got it reinspected with stock exhaust and now good for 2 years and now am waiting for my headers to get here. thats another way to get around it

my header deleted my cat, and I fixed that with a set of anitfoulers

, it will probably work for the mustang you just need one on each side,

buy a set of 1/2in anitfoulers from autozone (help partnumber 40002) leave one alone, the other drill out with a 1/2in drill bit, screw the modded anitfouler into the normal one and screw your o2 sensor into the modded one
so

o2 sensor--modded anitfouler--regular antifouler--exhaust ( do this on both sides of the exhuast for both o2 sensors)

and you have no CEL cause it limits the exhaust the o2 sensor sees so it thinks you still have the cats on.

or you can use a tuner and turn off the downstream o2 sensors or you can get M<IL eliminators.

with a good tune, that is done properly u will be able to pass, however if it is not done properly u may fail even if u cel is off, because the test will pic up that somthing is not reading right.
