I've been messing around a little lately looking at K&N CAIs for my '08 Tahoe, but I already have one of these K&N filters in the stock intake. Anyone have any idea if I would see any noticeable performance increases by going from a K&N filter to the full K&N CAI? I'd want to get a boost in hp and mpg if I shell out the money for it. Any differences in sound as well?
Also, I already have an exhaust. The Tahoe had it when I bought it so I'm not sure what brand it is, but I think it's a Borla.
