Did you disconnect any wiring while installing the bypass pipes?
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

So, I finally got around to finishing it. I ordered the o2 sensors, however, I didn't initially put them in because some reviews said they do not get CEL after installing....so after install went for ride, the sound is definitely nastier, and overall I am satisfied that I completed my entire fabspeed system....however, I was residential driving, and couldn't go too fast. Got to a road where I got hit it a little, after hitting it....here's what came on my dash....
Which lights are new, and which were left over from the Spyder tail light thread?
You mention that you have a "complete" Fabspeed system. Maybe you could list all of those items, along with any other recent mods?
Your PSM is jacked up (or currently activated, which seems unlikely), your PSM/ABS lights are both on (symptomatic of the taillight issue you posted about previously), your brake wear warning light is on...
You're not suggesting that merely accelerating with your muffler delete pipes caused 6 warning lights?
What is your voltage reading? Your photo doesn't show the voltage. It LOOKS like it's at less than 12v; if the car is actually running as depicted by the speedo, you should be at around 14.4 volts.
This is going to sound...disparaging?...but you need to STOP hanging new crap on your car and EITHER put it back to stock so it actually runs, or at least add and troubleshoot ONE item at a time. Also, actually explaining what is different now than before you "hit it" would help - otherwise, we're just guessing.
I installed spyder tail lights last Monday. Got abs PSM......took them off then put the DEPOS on Saturday.....no lights what so ever, went for long ride...nothing no lights nothing at all. Not one.
All I did today was put the cats on......
That help?
I have no clue as to why brake lights came on, and as to why my voltage is low...
Need some help
Dude, at this point nobody can help unless you can shed some light on how you wound up here.
What was involved with "putting the cats on"? You said you ordered some O2 sensors but did not "put them in" - what does that mean? Are you running with no O2 sensors at all?
You're going to have to describe in detail what you did before anyone can guess what's going wrong. Did you disconnect any wiring while installing the bypass pipes?
Ordered o2 sensor extensions, but did not install because some threads said they got no CEL by just putting sensors back without extensions. I'm running with all 4 o2 sensors. Disconnected no wires at all. Jacked up my car, took off cats, put bypass in. Only thing I disconnected were the o2, but reinstalled
How long was your car sitting for? That could've easily drained the battery if you have an older battery or have only gone for short drives recently.
Also install those o2 extenders. I don't know why you didn't just do that if you already had them, especially since you got the cat "bypass" and not the 200 cell cats.
Ok here's the update. Just came home from car show, turned 911 on, went for ride.....no lights, all well.....when came to a red light, my voltage dipped....when driving, came back up. I drove for 10 minutes. 95% of the ride, no lights and no voltage issue.....maybe this is an issue with the o2 sensors?
Sounds like a parasitic draw, a bad alternator, or a fried voltage regulator. If it was fine prior to the cat removal/bypass install, I'd start looking for pinched/cut wires. I don't know if the O2 sensor + heat wire is always live or not, but carefully examining everywhere you did work is 1st thing I would do.
ok, so heres the update.....anyone who is on this board that lives in central jersey, knows that robbie provost @ provost motorsports is the go to guy around here for porsches........took mine to robbie today....we checked it over....o2 sensors all good.....its just a coincidence that the same day i install the bypass pipes, my alternator decided to die.....its not charging at all...BIG THUMBS DOWN.....but, at least i dont feel inept
