Yes I am familiar with this issue from my hot-rod times. I've looked into the G37 situation and I did not find any configuration of the intake pipes to be RAM friendly. In my opinion they are just narrow air supply pipes hidden behind the front cover, not subjected to any force of air at speed. UCLA BRUIN had suggested installing the brake cooling ducts to help lowering the rotor temp and at the same time RAM force some air into the boxes. Look at your car and tell me what you think, peace, Greg
Do a google search. The airboxes acutallly work at speed to help generate a ram air effect. They make an additional 3 hp while in motion. This was first introduced on the HR motor and carried over into the 3.7 It cannot be published since the car must be on the open road. Opening the airbox negates this by causing a low pressure situation that will actually drive the air out.

If that is true (which I have my doubts) then he possibly opened up the door for more air at lower speeds or off the line.

I dont think so, you see the sealed air box directs the air into the plenum which is also sealed. By opening up the air box you are creating turbulance and also allowing air to escape once you get up to speed. The ram air really shows some benefit at higher speeds..

Exactly. Drilling holes in things isn't going to really improve on what the engineers designed to be reliable and produce respectable power. Reading these articles made my cringe, especially doing it to a semi-expensive car like the G. I guess I can appreciate the attempt, but you spent good money on the car, if you want to mod, do your research and buy good engineered parts.

Yes!!! Adam you are absolutely right! This is how I do my research and I will buy parts which make sense to buy. In a case of the muffler you don't have to spend extra 1000 bucks to get a little more aggressive sound, just drill the 3/4 inch holes where I showed you. By doing so you do not make your car less reliable. You are simply TUNING the car to your liking. Isn't it what we do here: TUNING? I do not deny the benefits of an opened exhaust with the turbo mods thou. To ease your cringe Adam, it is easy to revert to the stock option by simply covering the openings in the muffler pipes, not a big deal. It's NOT like I drill holes into any vital systems of the car, it is my baby too don't forget. P.S. Watch for some more drilling coming up soon if you are not faint at heart ! Greetings from Sarasota, Greg.
Wanna know who drills holes in their mufflers? ricers at honda-tech

hahaha Adam, it is funny! But to stay close to the topic it is necessary to examine the evidence[ the boxes] and figure out what to do to make'em perform better without spending the money first and analyze things before castrating out the whole factory intake system. I just made some gizmos I will attach to the boxes to make them sound better using the original parts made out of the resonators found in the sedan. Watch for the post soon.
