Garage List
2007 335i  [5.00]
I was warned of the smell, but idling in traffic or at the stoplight with the windows completely down, there is no smell.

The only time I can smell gas is when I first warm up the car in the morning in my garage. I think I smelled it outside of the car after a few mins of idling, but couldn't really detect it inside the car.

So not too bad. Maybe cuz the DP is new? Or maybe my OEM exhaust / secondary cats are doing a little work.

I'm guessing the guys who have gone full catless will smell a lot more (actually, feel free to confirm cuz I'm curious!)

I have been wanting to get catted (+ ceramic coated) Šr DPs for a long time. Anyone that can comment on catted vs. catless?
