Today was a frustrating one. I ordered a Speedtech mid-pipe w/ cats because my OEM cats failed after a couple track days (and are not under warranty). The muffler shop could not install the new mid-pipe citing that the location of the oxygen sensors don't match the original locations and the lead wire is not long enough to reach the post-cat sensors.

The manufacturer said that was never a problem, but didn't have a solution.

How can the mid-pipe be installed if the sensors are in the wrong place? It looks like the Fabspeed, Maxspeed, and Speedtech mid-pipes all have the post-cat sensor far away from the OEM part's location. WTF??

In addition, the cats do not have an 'EO' number which is apparently necessary for smog in CA.

Any advice is really (REALLY!) appreciated.
