M340i catless downpipe
Hello everybody.
I want to ask the ones who have catless downpipes installed, how bad is the smell? I want to get it, but I'm afraid it will be to much gasoline smell. Many thanks |

Just got mine on today, you'll smell it once when you get out of the car if you have a garage but it isn't terrible, if you sit in park and idle with the windows down for awhile you'll eventually smell it for sure but I don't know why anyone would do that.

I’m running catless downpipe on my m340. Yes it does smell but only if the windows are down and ur at a red light or parked. When driving u can’t really smell it. But the pops and burbles overweights the smell, making it worth it. Instagram @orange_m340i

Sport catalyst Wagner. If you go quietly it does not smell. There is a smell during aggressive driving. And many notice this behind. I live in the center of the city. This option does not suit me. Although I really wanted to put it for the sake of sound and power gain. |

I'm still no 100% on which one to buy.
Catless is best probably in every way, just having some trouble with the smell. Here in Switzerland I can have some problems with that, and so, I'll probably go with a catted one. OPF really kills the sound here in Europe. |

For example California recently got a law on how loud the exhaust can be. In New York, you won't pass annual state inspections if you have a catless downpipe.

I had this concern before I went catless. After living with it for 50k miles it's a non issue. I don't even notice it. However my friend always comments that he loves the way my car smells when I meet him in the parking lot at the golf course.

I don't know about NJ but NY state DMV doesn't give you registration renewal sticker unless they electronically verify that the inspection was done within a 12 month period. |
