how did you manage to bypass the second oxy-sensor?
If I inderstand it correctly, the two holes in this testpipe are for oxygen-sensors, one before and one after the cat. If you remove the cat, the second sensor will immediately sense that the cat is not perfoprming its function, and light the CE light.
How is this avoided? Is it the APR software?
Thanks,
Andrei

You will get no change in performance with the MIL, but yeah APR corrects it with software...
I had a testpipe with MTM software on the B6 and the MIL from cat inefficiency causes absolutely no change in the performance of the motor. cheers! Mike

CEL in a new car somehow irritates me (+)
having paid that much money for the car I like it to run smooth with no alarm signals pissing me off. We dont have lease here in Russia, so you buy 'em upfront or get a credit to do so.
