You can draw more air through the throttle body if the air is not restricted. I put my K&N in the stock air box, on the Shelby it has two air horns one cold air and one under the hood. It did help with no noise. I also have a 3" dual exhaust cat-back system, MSD w/coil and Shelby/Mopar performance computer. I will have headers and ported and polished throttle body.

You can't draw any more air than what the throttle body will allow in.
There should be no problem for the stock exhaust system to handle it.
While on this subject. I read with interest all the mods everyone is doing
to their air cleaners. All the open element filters, flipped top covers
etc. This is all old 1950-60 technology to increase air flow. You may
think your getting an increase in performance (and you might get a little)
but I think your just getting more noise than performance gains. First,
your sucking hot under-hood air into the engine which everyone knows is
less dense and produces less power that higher density cool air your
original system was drawing in from the front of the engine! I would think
that opening up, but retaining, the original air system to allow more air
in would be the best way to go. Like maybe the following:
1) Install K&N filter in original housing
2) Remove original air horn from housing and replace with larger fabricated
unit.
3) Install larger diameter tubing to fit new air horn.
4) Rework or replace front air intake to fit new tubing
Even with these mods your engine can only draw in as much as the throttle
will allow. If you increase the throttle body size then the exhaust will
be the restriction. If you increase the exhaust then the Cam will need to
be changed. It goes on and on until your wallet is empty and your wife
and kids are gone!
