Well, you are letting your engine breathe better and if you look at the stats its something like 10hp(they say) with the K&N and maybe a little more with an exhaust. You will notice a little more urgency out of it but it's not a crazy difference. I highly recommend adding a SuperChips to your rig (along with the intake and exhaust) if your looking for that performance increase without having to spend thousands on things like internal engine work.
