Surely there must be some cars with exhaust, remapped with both CAI and stock box?

'Heavily modified' is the wrong term.. more like heavily bolted-on modded is what I meant. But the OEM setup
is pretty restrictive, especially considering the 2 cats on the exhaust system. The engine is just basically an air pump afterall.. it can't draw in more air if it can't spit it back out at the same rate.
Restricting the exhaust might possibly restrict the intake as well is all I'm saying. So if you put in a more free-flowing exhaust system, maybe the better intakes will start to show themselves. But I didn't do any before & after air flow tests of my intake with my other mods, so it's just conjecture at this point.
