Screws with Emissions??, here we go again..i KNOW! Options

[Rook]

Ok. I know its been discussed thouroghly but i'm not wanting to go through all the threads trying to find out how many ppl's emissions got messed up. This is about the ebay header. I'm wanting to put one in my Celica but i'm not sure if that'd be smart since i've heard it messes up your emissions. I was then told some ppl say it does and some say it doesn't. I want to know how many of you guy's emissions has been screwed up by the ebay header. Input deeply appreciated

If you've used a different header your input is appreciated as well

on a '98-01 Camry there is a motor mount directly to the left of the header (facing the car)
i call this the "oatmeal can" mount since that's what it looks like to me.
the crossmember is mounted differently which will not allow a Celica 5sfe header or a 3sge header to fit correctly on a Camry.
This crossmember is what allows a 1mz-fe to be a direct fit in a Camry, but not in a Celica.

However, I do know that a Camry header is a direct fit in a 5th gen Celica. In a 6th gen Celica ... I can't say 100% yes or no direct fit. I know the bolts will fit on the head perfectly, but as far as the exhaust goes ... you may have to take it to a shop for some custom work, but shouldn't be a big deal.

1 other point to add ... Unless the Camry is a Cali spec model - there is only 1 Cat in the midpipe, not 2. Fed Models (all other states spec) have only 1 Cat in the Midpipe.
Everyone gets this wrong all the time.
The 3sgte has 2 cats 1 in the Downpipe & 1 in the Midpipe.

As far as emissions goes there is no reason it should ruin your emissions as long as you replace the O2 sensor as needed per regular maintenance.
What the header may do is cause you have a CEL --- this is common in Camry's (not sure about 6gc's) but a J-shaped bung that can be bought at stores online may solve this problem.
I'm going to be buying a header + midpipe (b-pipe) for my Camry soon so I can report back regarding emissions, but it shouldn't be anything that wouldn't allow me to pass easily.
