Alright this past weekend i got my UIM from 60V6 store. And well i got Phenolic spacers too. Ive noticed since both are installed my exhaust is quieter and the car runs a hell of a lot smoother,is this normal and if it is what causes it?

I cant think of anything that the spacers or UIM would do to make your car smoother. However, when you replaced them you may have sealed up a vaccum leak somewhere. That would definitely make the car run smoother.
