On the intake side, the restriction keeps debris out of your engine and, to a lesser extent, mutes the induction howl.
On the exhaust side, the point is to keep the engine reasonably quiet and to keep emissions legal.
IMHO with any aftermarket intake or exhaust system you are going to make some compromises for the increased flow. Those compromises may or may not be acceptable to you.
