Catless downpipes and home garage
Hey guys, sorry if this is a dumb question or what not but is there any risk of carbon monoxide poisoning with the smell lingering of a catless setup in a garage connected to our home? And is there any risk of it during long drives if say windows were rolled up the whole time and the smell was quite potent?

There should be no smell with windows up as long as you installed correctly (bolts tight and good seal with the gasket). Only smell would be out the tailpipes. Personally I think catless dp and 200cel high flow cat in the midpipe is their perfect combo of power and decreased odor. And that's exactly what is happening to my car now (get it back on tues) |

just so you're aware carbon monoxide is completely odourless.
I'm not a fan of running completely catless. if you drive nose first into the garage you should be fine, also move the car out as soon as you start it. definitely don't idle the car in a confined space. |

I start up my car all the time even with the door closed (for about 1 minute or so before I leave) and I have had no problems, the smell even goes away before I leave and the door closes.
No worries, just don't sit there for an excessive amount of time with the door closed/windows up.
