Hey all, I've been having some real problems with exhaust smells in the cabin. It's so bad that I get headaches, so I'm hoping I can fix it. The only problem is I don't know where it could be coming in from. Where are the common spots that exhaust could be coming into the cabin?

Thanks for your help

Catalytic converters. Biggest one I can think of. Check all the seams. From engine to header, header to pre-cat, pre-cat to cat, cat to connecting pipe, connecting pipe to muffler. I bet you have a bad cat though...Ive have 4 RX-7s right now, but none of them have good cats, and they all have exhaust smells in the cabin...
