are breathing mods pointless without getting an aftermarket exhaust?

I have a pop charger and want to get a spacer, i know the gains are minimal but are they even worth doing on a stock exhaust?

 

They are not pointless at all. You will get more from them with exhaust, but remember, dyno's and claims are usually based on stock cars with the mods, not modded cars with additional mods.

Exhaust mods will compliment intake mods - not enhance them.
