Exhaust Fume Smell Through Air Vents

Hey everyone, I changed out my exhaust to a fully Catless no res x pipe x straight pipe all the way. It was too loud so I changed it back to stock. I recently started smelling fumes coming through my air vents when I use the heat. It never smells when I use cold air though. I can smell the exhaust fumes from the outside too when I start the car. Just wondering, could it be the exhaust gaskets? Any DIY for a smoke test to see where it's leaking?

Thanks for reading, any advice much appreciated!
