Car reallly fumey

[DaNEWgUy]

I just recently bought a s14 with hotshot headers and a apexi n1 exhaust. The guy told me he had to get rid of the cat when he put that on. Whenever I drive in it I smell these fumes almost like gasoline but not. Is this normal or is there something wrong with my car?

Header may not be bolted on tightly. Check all the seals, gaskets, etc.

that pb blaster stench never goes away. just hope it's that. i used some of that when taking off my intake manifold a few months ago, and my car still smells...like gas.
