Need some advice. I installed z1 hfc and a catback exhaust. I used the z1 gaskets on the hfc with no rtv since it’s not recommended. I’m getting fumes in my cabin whenever the HVAC is on, recirculate or not. I took it to two different exhaust shops, one says that I have a leak at the manifold to cat flange because all the aftermarket gaskets are ****, and the other shop found no leak. The only recommendation the 2nd shop said was to check the cabin filter but I put one in roughly 6mo ago. I have found nothing from searches so I’m pretty clueless. I figured I might just have to get back under and rtv the gaskets.

I also have a Stillen g3 so I was thinking maybe there’s a cracked line from the pcv system but couldn’t find any.
