Atlanta F30 335 with Catless Downpipe?

Anyone in Atlanta (or the outskirts) have a 335i with a cat-less downpipe installed? Looking for someone specifically that has a F30 335i with MPE as well as de-catted so that I can get an idea on how bad the smell is on this car before I pull the trigger on my 2013.

Have MPE but why would you want to do this? You'll have to reinstall the cats every year for emissions test and it DOES stink. I had some jackass in a cat-less Camaro ripping around work parking lot and the exhaust stink was nasty. It's also really f'ing bad for you.

Is that worth the what, 20hp you might gain?

I have car registered outside of Atlanta and don't have to do emissions. The 20hp gains would be nice, but I don't know how much the smell would bother me. I have another car that is decatted, but it's no turbo so doesn't have the same smell issues.

It’s not bad at all. The only time i smell it is when initially pull into the garage. It’s way more then a 20 hp gain when you add up a stage 2 + flash, more like 80 hp and 100+ in torque. Plus it sounds so good.

Hey man I'm in Atlanta too and need to pass emissions. What all do I need to register the car somewhere else in GA?

I think you can get by with having mail delivered to a friend or family’s address in that county
