Sorry, sorry, sorry...

I know this topic has been covered before, but I just unplugged the orange plug and my car sounds fantastic! But I did a thread search on this topic and somewhere, someone mentioned that doing this will result in a CEL (mine hasn't yet)... I can't find an explanation on this forum, so please can someone explain this? Why is there a CEL when you unplug? Does this cause some permanent damage? If there's a CEL, should I just plug it back in? Then when can I unplug again?

Thanks!

I have been running mine with the plug off for the past 3 months (6000miles) .. and there havent been any issues.

No damage, no CEL - urban myth.

Jimmy - Ditto on what he said --^-- no CEL

I've had mine unplugged for nearly 3k miles and no problems and no CEL. I plugged it back in for a day and couldn't believe how much less satisfying the car sounded, even with the switch on. I think PSE sounds 20% better at all RPM's with the wire unplugged than it does with the wire connected in any mode.

I blew out the baffles in both mufflers with the switch unplugged. Replaced by Porsche under warranty, no questions asked.

Thanks! That's the end of that.

Is it possible that your original mufflers were defective?
