I just installed a catted dp and got a couple of CELs.

I'm wondering if anyone knows if these are the expected CELs from installing a downpipe or if I have something else going on that I need to address.

if it’s a high flow downpipe it should be expected to have codes and you should be running a tube like BM3 to counter that.

Hello,

I expected some error codes. I'm really wondering if these are consistent with the codes for a dp install. I was expecting something like p0420 not p2096.

Does anyone know what codes BM3 suppresses?

the codes are says that your system is running lean and your 02 sensors are responding too slow. Could be a leak or bad 02

Ive been running a VRSF catless downpipe and used an O2 defouler with success since april. Ill link it to the exact one I used.

after a year with the defouler mine finally threw a code and even after changing the rear 02 sensor same code still pops up 1 to 2 times daily.
