CP-E catback + AMS HFC =
Absolutely amazing!!! The sound is orgasmic. Quiet when you need it and absolutely screams when your on it. The tone is very deep and throaty I love it. Oh and I have zero drone. Great products to both companies!
I think I peed a little....

I believe it's because of the o2 sensor in your HFC. The mechanical fix for that would be that o2 sensor extender thing. I think a tuner could turn it off when you get it tuned, too.

I had bought one of those code readers last year so it was a good time to try it. The code it read was for the cat so I cleared it but I'm sure it will come back.

Sort of, but it's a bit different. The AMS spacer restricts the amount of exhaust flow to the sensor by closing off the hole that feeds the sensor, this variant physically moves the sensor further out from the direct exhaust stream and allows for multiple position configurations to combat whichever code you are throwing.
I would recommend installing the sensor extender facing downstream, towards the back of the car, especially if you are running a HFC, because you don't want to take it too far and throw the O2 sensor activity code. Some people with aggressive setups with test pipes who still see P0420 codes even with standard spacers may want to use it with the "L" facing upstream to remove it from the exhaust flow as much as possible.
The other benefit of this style is that if you are seeing your typical P0420 code and you add this spacer with the "L" facing upstream, furthest from the flow of exhaust or a regular spacer (or two) with a tiny hole, sometimes it restricts it too much and then you get the O2 sensor response code instead of the cat code. With the 90* spacer, you would then just flip the position 180* so it is downstream (pointing to the back) and sees just slightly more exhaust flow so it doesn't think the sensor is inactive but is still far enough out where it doesn't throw the catalyst code.

I will have to pick one up thanks for the info. I haven't gotten the code again since I cleared it but might as well solve the issue for good. I hate seeing that damn light haha

6 months CEL free this way. Its worth the cost to keep that light from coming on.
