well, the air intake probably changed the amount of airflow so now
the computer is over compensating for the increased air by enriching
the air/fuel mixture.

Dump the air intake and go back to stock. Contrary to popular belief,
it's not going to do anything except make your wallet a LOT lighter.

As for the exhaust, take it to a muffler shop. That's a nobrainer.
