    cats necessary to pass emissions"

    My exhaust went tits up on Monday. And, I just bought headers, midpipe, and muffler to replace it. Have any of you guys passed the sniff test without you catalytic converters? Trying to decide if I need to buy some high flow ones and weld on.

    You will not pass without cats, you might even have trouble with the high flow cats.

      I failed with a Magnaflow cat. Barely.

      I put the OBD2 cats back on and had no problem. (DOHC motor)

                        That only works for one year, you will be required to pass emissions next year.

                          Here's what he meant:

                          Emissions testing in Washington is only required for cars that were produced in late 1986 and later. Once a car is 25 years old, emissions testing is not required anymore. Also, Washington only requires testing once every two years (unless it gets sold). So if the OP can pass emissions on his 88 E30 one more time (whether using Seafoam, or a catalytic converter, or waiver, or whatever), he shouldn't have to pass emissions again.

                              My 96 Passat VR6 has waived every test since about 2000.
