Muffler Delete and Emissions

Ishan99 · 07-07-2019, 02:21 PM

Hey all! I recently did a muffler delete on my N20 320i. It's a 2017 car and I'm not really sure when I'm supposed to go for emissions testing. I bought the car in 2016. I know for the first few years, I don't have to get it tested, but I'm not sure after how long. I am located in Atlanta Georgia, but I'm not sure what the laws are. Will my muffler delete pass an emissions test? Or will it fail?

Muffler delete should have no effect on emissions.

I’m in the Atlanta area as well, I did my emissions test after I did my muffler delete, resonator and stock downpipe still on and I passed. No problems

No effect.... but don't forget some emission test site are jerk and will do visual inspection.

My State of California... say new car don't have to be smog for 8 yrs...lol. but if you read the registration statement every year...you already paying for your pollution $20. It goes to the state and it's an FU to the smog centers/ station.
