Fabspeed high flow cat CEL

Hi guys, I installed the fabspeed high flow cat with resonated xpipe months ago and had about 2000 miles on them. Yesterday I installed a set of lowering spring and today the CEL came up. i thought the O2 sensors that fabspeed claimed would keep the CEL off. Should I get a ecu tune or I just need to drive for a few hundred miles more and it will go off? I chose the high flow cat before cuz i didn't want a tune but if i have to tune it i'd rather make it catless. What do you guys think?

That's the problem with HFCs. It'll probably go off in a few hundred miles. But will start to pop up more frequently.

you have 3 options

1. call the fabspeed and ask them for O2 extender

2. get the akra Delete-R

3. flash your ECU

Any kind of ECU flash would work?

How do they work? and where do they fit in the exhaust system?

When the CEL came up today I felt the exhaust made more noise than before, is it me or possibly there's a loose clamp or something that caused it?

all it does it place your 02 sensors further down the hfc pipe. They go right in where your plugs are now.

The extenders worked for me. Problem is you have to drop the exhaust to get them on ; (
