Hey guys I recently put some 034 down pipes (no cats) in to replace my piggie pipes. I did some test drives and everything seemed great but I drove it today and got a cel. 2 codes P1176 - Bank 1: O2 correction behind catalyst: control limit reached
P1177 - Bank 2: O2 correction behind catalyst: control limit reached. I'm running the big defoulers which always made my rear 02s happy.
The only thing I can think of is I might of mixed up the passenger side with the driverside. I'll get the car on a lift soon to check. I have mtm software so as far as I know they don't code out rear 02s :( Anybody have this problem before? Or have these codes come up? Thanks guys
