bought some used apr version 1 DP's. did throw codes at first, but they threw a few in last couple of days. just the cat thermal heat up too slow code or something like that.

Default Hmm... I'd try contacting APR and asking them for a solution...

Since it's their downpipes?

Default are you running the downpipes WITH cats or WITHOUT?

If without, you should be throwing codes.

If with, you should call APR and send them your codes.

Default its related to having only 1 - O2 sensor hooked up per side IIRC

you'll need to send your ECU in to ignore that code.

Default Didn't the Version 1 of the APR downpipes not include O2 sensors? Wasn't that the big design change

with Version 2?

Pretty sure the Version 1 of the APR cats didn't have that sensor...
