Hi there!

I have long tube headers with no cats, usually the check engine turns on for the error tryin to say that i need to change my cats because their performace is not good, obviusly they are nor "there", i try to weld another nut spacer for the after o2 sensors but the still turning on the light for that cause, i have the diablosport predator and with this i delete it.

somebody can tell me what can i do,

You'll probably still get the CEL with headers and a high flow cat. Weld yourself in a bung on each side after the cat and use non-foulers.

If you don't know what non-foulers are search the DIY section, I have a how-to in there...

 

Agreed. I went with non foulers cause i wanted to keep the rear o2 sensors in a readiness state vs having them turned off by a custom tune.

Been code free for 20k and just passed emissions 2 days ago by them doing OBD and gas cap check.

 

I kept my stock cats on my 3rd Gen when I did LT headers, just moved them back and extended the O2 wires. On my old 2nd Gen, I omitted the cats, did the non-foulers and never had a code in 60,000 miles plus...
