    Well the title says it all..
    After installing a WAI, my exhaust smells upon acceleration.
    It's not like a have a bad cat smell, it just smells like exhaust.
    A friend of mine has a WAI on a 95 Stang and it does the same thing, so i am curious if this is just due to the intake being put in, or perhaps the exhaust is being pressured more, any opinions guys?
    Or should i just suck it up and deal with the smell?

    It's a grand prix though, cut the cat out before it fails on you anyways.

    Because, 90% of the time...it will.

    N/A?

    Doesn't really matter.

    S/C?

    Probably wouldn't hurt, but I'd address the downpipe/cat/u-bend first.
