6G Celicas Forums

Will they stand up to a long trip? (say, 700-800 miles) or will they overheat and cause problems?

yes.
no.

Thanks! One more question, and I know this is state-specific. If I install the header, make a bung on the downpipe for the 2nd O2 sensor, and install a cat convertor after it, will I still pass inspection?

Don't see why not.

Thanks guys.

i beat the hell out of my car, just make sure to wrap them

Wrap them if you want to crack the welds.

Yeah, wrapping them cracks the welds. Happened on my dad's AE86, he then told me never to wrap a header and proceeded to curse.

Hector I unplugged the second O2 I don't know if OBDII guys have a problem without it, but I know my 94 runs perfect, no CEL...since you have a 95 I would presume you wouldn't need it either. I also removed the cat...and just FYI I've driven it from NY to NC and header is OK. I have had an issue with the 2 to 1 pipe loosening up. I ended up putting two nuts on, also had to make myself a new gasket for it because the original fried after repeated loosening and tightening.

i have a 97 and i ran without the 2nd O2 sensor and no CEL.

I'm getting a shop to extend it so I might as well have them weld the 2nd O2 bung, ya know? And I want the exhaust to sound as good as possible, so I'm going with a hi-flow cat.

no o2....incorect air fuel ratio = overtime bad!

I have had the header on my car for more than a year now, its wrapped and no issues out of it, keeps bay temps down

There is really no reason to want to keep engine bay temperatures down. There is nothing that will melt around the header. Wrapping them will cause it to fail prematurely.

I dont have a secondary o2 either, never had a CEL problem. The headers will last fine hector. I think its more of a time thing that milage..

^ Thats what I think



thats what I think

Alright, well I'm ordering a hi-flow cat and getting my header sent to me from home. Hopefully in less than 2 weeks, I'll have it all buttoned up.

I have headers on my 94 celica and i drove it from Stevens Point Wisconsin to Houston Texas with no problem at all

what if i go over the welds with another layer of weld, then wrap? would they still crack?

or if i dont wrap around the welds, just the main sections of pipe

is there any real gain by just a header,or r u guys running a full exhaust?
