Hey guys, I have a 2015 BMW 220i with a muffler delete and I love it
.
I am thinking of going to the next stage of getting a catless downpipe to get more crackling from the exhaust. Im faced with 2 problems
1. removing the cat will trigger the o2 sensor and create an engine lit
2. removing the cat will make the car smell bad
ive heard of some adapter you can put on the sensors for it to not trigger im not too sure never seen where i can buy one...
any ideas guys? greatly appreciated
p.s does anyone know how many cats there actually are on a 2er
also thinking of doing a mid silencer delete, what do you think
or are there any other options to make exhuast crackle
