MY 89 auto. Having an X pipe installed - mechanic indicated that the "check engine" light would probably stay on since we are taking the cats off and all the plumbing with it. Is this the case - is there something that can be done so this does not happen or is the mechanic misinformed. Appreciate any help on this issue. Thanks.

As long as he reinstalls your O2 sensor into the bung on the X pipe, all will be well.

"Check engine" light? There is no check engine light.

There is in my '91 digital dash.

your mechanic is misinformed, he is missing something. Did he take the handbrake off to see the light go away?

Bill Ball

Right, but not in 89, just to be clear. Started in 91 USA/Canada cars.

(BTW, I am more happy there isn't a problem and Im sure your gonna love the Xpipe!)

Stick the mechanics head by the tail pipe after the install while you mash the gas. Then say, I didnt see/hear no check engine light haha.

I've put an x-pipe w/o cats on an '87 S4 and '93 GTS, no lights in the dash on either.

The mechanic is a good mercedes guy and has completed some tough jobs on my SL 600 - he' not too well informed on Porsche auto's.

We don't have lights; just that one that looks like a belt on 2 pulleys with 'belt tension' written next to it that is supposed to put the fear of God into you.

So the "real" question is, how does she run with the X-PIPE???

X pipe installed along with all air pump, cats and assorted plumbing removed. Car sounds a bit deeper but not really louder. Can't really tell if it runs stronger at this point but will figure it out in a few weeks. Car ran great before.
