It seems like my SS Cat'd Y-Pipe might be toast. Fail Ca. emission on the 25 mph roller test(nox too high). It either the cat's or the EGR. But my first '90 SHO would pass emissions with a choked up egr no problem. So I think it time to liberate the SS Y-Pipe to improve perfomance, but in the mean time I need to get ahold of a stock Y-Pipe to get past the smog check. Anybody in the bay area have a stock y-pipe they would be willing to loan, rent or sell?
Let me know. Thanks.
