Default Can't Hear My Intake!!!

I was wondering..can you guys hear your cold air intakes inside your trucks??I have a spectre cold air intake..and when the hood is open, i can hear my intake. while i'm driving the only thing that i've noticed is a distinct growl when i step on the pedal..is that all i'm supposed to get out of it, or am i also supposed to be able to hear the intake's sound when i step on the pedal? couple things..

dual exhaust.
not straight piped (i think this may be why i'm not getting the sound i want up in the front of my truck.)

lemme know.

That's about it really. It all depends on the design of the intake as far as how much noise is transmitted back through the intake.

I think that 2001 was the first year for the pre-cat. So right after the 'Y' in the y-pipe will be the pre-cat which is about the size of a medium coffee can. Then there will be the catalytic converter and finally the muffler before the tail pipe.

Here is a picture from RockAuto.com:

As I understand, the pre-cat is used to help the main catalytic converter do its work. I wouldn't go mucking with it.

This from Wikipedia:
"Many vehicles have a pre-catalyst located close to the engine's exhaust manifold. This heats up quickly due to its proximity to the engine, and reduces cold-engine emissions by burning off hydrocarbons from the extra-rich mixture used in a cold engine.

Depending on your location, you may be required to install another catalytic converter for a true dual setup. It may also be in violation of the emissions laws to even modify your exhaust for true dual setup depending on the local/state laws.

I have a spectre filter on my ebay style intake. It "slurps" is about the best way I can describe it, more like a vacuum under the hood, haha, like you have a giant air leak! You definitely hear the engine coming out through the intake but that is generally when I'm romping up a hill with the windows down, lol, windows up and I can barely here her at all. IDK though, I bought the 3.5" tubing and spectre filter for more air flow, as opposed to wanting my truck to "sound cool". hope it helps.
