Cat Codes

spooled2 · 03-10-2015, 04:42 PM

Dealer says I need cats. What other options are there for me to replace them. Was thinking down pipe without cats. I did some research and If I go that route I would either have to get them with the secondary 02 bungs or install bungs to keep Engine Light off.

Also was wondering if my bottom 2 02 sensors are lazy wouldn't that set a code. Anyone know how I could check that or suggest a scan tool that is good for BMW's.

I find most cats to be lazy. Many of them sleep all day.

Replace your cats? I love my cats. I don't know what I'd replace them with, because I'm not really a dog person tbh.

these guys. If you run any tune JB4/Cobb they'll surpess the codes from popping up. O2 bungs or simulators will not work on these motors.

If your car is N54, I have a set off of my car with >5K miles. Yours for $200 or $500 installed.

So I put the bungs in and cleared the code and the light hasn't come on.
