Header information?, Update! Please advise! Options

***Update-6-29***

I need to buy a new header, my oem is horribly cracked w/a half-assed weld job, and the heat shield is cracked and missing half the bolts. I've searched the site and found that most of you have bought the ebay aftermarket header(typically for the corolla), and have to do some modifications to make it fit(i.e. welding an extra piece of pipe, making a second bung hole for the second o2 sensor). That's all fine with me if I absolutely have to, but was wondering if anyone has purchased the one from M2 Performance: http://www.m2performance.net/product/produ...?productid=5932 Supposedly it's just for the Celica, or are there still mods as mentioned above? I'm not sure I even have the second o2 sensor as I have not been able to get under my car yet, and I have only an all stock 1.8 ST engine. Ideally I'd still like to be able to pass emissions though, so I don't know if this modification is worth the hassle if I can't pass emissions without a stock header. Thanks for any info you guys can share!

I can truly say you need to get a 5sfe ebay header. 4-1 - its really what we only have. you can use a 3sge header but it becomes more work cus you gotta pipe the rest to meet your exhaust. i have a spare 5zigen exhaust but would probably cost like 200 bucks or so to ship it your way, even comes with a test pipe if you need it. I noticed you are in cali so deleting the 1st cat, would put you in a position where I cannot guarantee you can pass cali smog test. just check anywhere online for the 5zigen bolt on, i remember there was a thread that mentioned someone had the site that had it available
