okay i just installed a aftermarket cat not that long ago to pass smog.. when i take my car up to 8200rpm..it'll smell like coffee .does it have anything to do with the cat or my motor is going out ?

 

you got a very rare and special integra it turns motor oil into coffee. Just pull the oil pug and pour urself a hot cup a joe. Never heard of anyone using the smell of coffee to describe wat a motor smells like when its on its way out. But it mite have something to do with you taking the motor to redline.

 

it's your cat, your breaking it in
