Title says it all. Got my enthusa pipes in today (they look amazing. jason does most excellent work.) and i'm trying to find some one on the east side of dallas to weld in a wideband 02 bung and fab a down pipe to replace the stock one that is welded to the cat. Would like to get it done tomorrow if possible.

We (Vorshlag) can do that work, but not on that sort of notice. We're usually booked about three weeks ahead.
Talk to Steve Kan @ PRT Performance, Lewisville.
Another vote for ARTech if posible, the best work of anyone I've seen, ever.
