So after the decision to not pay 3x more for the AA downpipe, I installed the CTS downpipe with the CTS o2 spacer. 24hrs in and no CEL at all.
Oh and I gotta shoutout mike@x-ph.com I ordered from y’all and it got here quicker than Uber eats😂.


And yes, it sound amazing. Still not as loud as I’d like so next step will be an AWE track exhaust. Need maximum snaps, crackles, and pops!

I would presume you have made some heavy pulls? Keep us posted, this is something I was looking to do as well. The concensus through most forums is it will eventually trigger.

Your presumption is very correct 😅 heavy pulls done. I feel a quicker throttle response (I promise it’s not in my head)
I’ll update this thread if necessary

Hey can you please let us know if you have driven over 50+ miles and if CEL has came on. Also which O2 sensor do you install it on, the top or bottom one?

Definitely driven over 50 miles. Installed it on the rear o2 sensor.

No CEL…

Report back in a month or so.

Hoping for the best, but in my experience it will trigger the CEL after 2 or 3 cycles.

[GXDFTHR]

Alas… CEL has popped up, it went away and came back. But hey, if you focus on the road ya won’t see it😅😅😅.
It’s not an issue for me, but I wanted to try the spacer anyway. Doing the femto unlock in the near future so not pressured about the CEL.

Dam, I thought we had some hope.

Few other o2 spacers that you can try including some with small cats in them.

I've tried them all. No go


If you're getting a P0420 code a resistor may work. I have the one, but I just don't have the time right now to work on my ride.

They made the newer b58s very sensitive while the s58s have no issues with spacers.
