Hey, I'll be ordering the OBX Header made for the Corrolla 1.8L very soon and I was just seeing what kind of feedback I could get. I know of lot of you have done this mod, so what kind of problems did you face and how did you get past them? What did you notice performance-wise afterward? Thanks!

Good luck. I think almost everything OBX makes is a myth. Most of the parts don't exist even though they're on websites.

Performance...expect a couple hp if you've done everything else to help promote flow (intake, exhaust, etc). You'll have to modify it where it goes over the crossmember and you'll have to weld a fitting for the second o2 sensor I believe.
