hey guys, im just being cheap. i don't have a aftermarket on my 350. but i want the growl. will cutting a whole in the front, yet retaining my stock piping create a growl. because for me, what i think is that the minuscule performance added from any aftermarket intake is not needed for me. any advise?

so, holes with joez? or no hole with joez? are you against holes?
i know for sure i don't want a short ram. Cali gets pretty hot in the summers.
i think i didn't make it clear, i don't want f-sport due to the price. i think you would prefer f-sport.
F-sport is basically a joez pipe with stock intake box which has a hole in front, with a license. Correct me if i am wrong.
my ultimate question is, with the stock intake pipe which is around 3 inches. which is quite big already. With an opening in the front of the intake box like a f-sport intake box. Will it create a deep roar sound similar to the f-sport?

i'd think it'd make a difference in sound(it can't get any quieter thats fer sure), i put the joe Z tube on my friend's car and honestly i couldn't hear a sound difference. if there was, it was very very miniscule. so if that by itself doesn't do much, the holes make most of the noise

i agree with the both of u, i have no need for the minuscule increase in power, if any at all.
but i do like sound. not loud, but something subtle, deep roar.
i might drill, will let u guys know IF that happens.

Yes it will make a difference in sound,
But before you drill try removing ur intake snorkel if all u wnat is sound (perf will drop slightly but car will be more responsive).
If you want, test it out, try removing the intake snorkle. search on here for instructions. Its REAL simple and effective. Sounds aggressive as hell.
IMO Unless u get the Joez dont cut holes.

! you are flooring for the sound @ 3.5K rpm right?

I bought a joeZ and I plan on cutting a big in the front of the box and then installing the snorkel back on the front. I did notice a lose in gas mileage as well. Ill keep you updated

Great thread first of all & Great discussion.. 
It always amazes me when people with no productive answers and no input about the discussion, can't refrain from clicking on this button..
Hey Koz
For the record, the OEM IS-F Intake Box and F-Sport Intake Box are very different in design... (not even close)
However, you are right about the V-8 IS-F needing more air...
Above 3,600 RPM's, the IS-F air box has a vacuum controlled door that flips open to suck more air in from the passenger side fender compartment.. During normal driving, the air is only sucked in through the one ram air scoop... When you floor it or pass 3,600 rpms, the second stage door opens and allows more air to flow into the box compartment.
This is why it carries the term "Two-stage Intake System"
Moving on to the F-Sport Box, I would "think" the hole is there to aid additional airflow into the air box under heavy acceleration...
I am sure there is an increase in noise.. However, I can not comment on whether there will be a power / torque gain or loss.
The hole is open all the time in this case.
Hopefully, this info will be provided by Lexus and their wonderful R&D team.
Since I would think they tested & dyno'd this set up many times...
I am Glad to see they finally caught on, on how to smooth out and optimize air flow in the IS intake system...
Which I have been doing since 2002...

P.S. - The hole in Air box is an old school concept / trick that many TRD performance part owners have done in the past on their own Toyota's..
