I was thinking the same thing but ill take a look tomorrow.
BTW did anyone notice MPG loss doing this or is it just that im a horrible driver?

Shouldn't affect mpg at all since it's only diverting sound to the cabin. Love this little mod btw.

Wes · 12-21-2012, 03:31 AM

Yeah you're probably just on the throttle more to hear the sound therefore affecting mpg, i know i am lol

86•BRZ · 12-21-2012, 03:53 AM

Oh c'mon. There is no way this can affect mpg!

Just did it and got the app read it as 2 dB louder at 5000 rpms. Haven't taken it for a drive yet so I can't speak to that and I'm not sure about how accurate the app is, but there seemed to be a difference to me.

I hear more tapping at idle too but that's because you hear more engine noise. I like it. FYI the soundtube just pops out from the rubber hose, moving it back and forth helped me. And also, there is foam inside along with a cross section of plastic, and 2 small foam pieces (on the sides). I removed all foam with a drill-bit and left the plastic cross section. I would recommend leaving the side foam pieces for others, they're small and could maybe reduce the idle tapping? who knows...

I did this mod yesterday and I would describe the sound difference as maybe slightly louder but more mechanical. I like it. Reminds me of some of the older (60's & older) sports cars. The side foam came out with a touch of the drill bit and the foam piece down on the plastic cross section just pulled out with needle nose pliers. I saved this foam plug in case I wanted to put it back, but I don't think so.

I have that same sound. Although to me, it sounds more like a old GM horn, very lightly.

Usually only in 2nd or 3rd shifting.

Anyways, I have full perrin intake and i've capped that tube, so I doubt it has anything to do with that.

Osiris · 04-04-2013, 02:42 AM

I did this mod a while ago, It definitely changes the sound a bit, but after adding my Invidia N1 I can't even hear the sound tube. All the sound is behind me. No complaints.

anyone ever find out if in the elbow before the one that goes into the firewall if there is cotton ball and whatnot as well?

No I just checked it has nothing in it, its just a regular plastic elbow.
