Hello.

My Dad has a 2016 2500HD GMC. while ago did a delete kit with a 5 inch exhaust and GDP TUNE. Love everything about it but eventually got sick of the diesel smell that’s just awful and can smell from a mile away. Is there anyway I can get the emissions back on and everything, will that get the smell away. Personal Mechanic that did it all threw all the stuff away. Wondering where I can get everything and if this will all help the smell or do i have to get a stock exhaust as well. The Tune from GDP will still work with emissions as well so that’s fine

Search craigslist for an exhaust or call some local shops and find the CAT and put it back on.
