Hey, I am looking into purchasing a catless borla downpipe for my 2015 ecoboost and I was wondering if anyone could help me as to the smells that come along with it, I know there will most likely be a smell while idling but would there be any cabin smell or a/c filtration problems that would come along with it? Thanks for the help!

As long as you're not running the car inside a closed space like a garage there shouldn't be any smell at all I wouldn't think. The exhaust gases however MAY smell like fuel a bit when running catless. Just make sure you get a proper tune to accompany the removal of your cat.

Correct ^^ I am running a 3 inch catless dp to a 3 inch full cstback and do come across a slight smell, but nothing out of the ordinary from going catless . HOWEVER!!! Remember that if you do go catless , you will have to get a catch can with a check valve and gut the pcv Because you might get smoke on idle .
