Default Intake Silencer delete elbow

when taking out the intake silencer on an STi..is it worth replacing it with the intake silencer delete elbow since it would still have the ram air scoop doing its function?
id like to hear my turbo/recirc valve more thx

I'd recommend keeping the elbow so you get the cold air from the front of the car. I just cut off the silencer box and sealed up the elbow myself. However, you won't be able to really hear the factory bypass valve. You will hear better spool, but can barely hear the bypass valve even with the radio off and the windows up.

That's really up to you, but don't expect a huge difference from it. I don't think you'd be able to notice it by driving. Maybe try searching for opinions on that filter.

If anything, aftermarket filters are worse but will extend your change/re-oil interval if you do not wish to keep track of replacing stock filters.

Regarding removing the intake resonator with or without an elbow, just be aware that there is little if any performance gain. Without an elbow will net you some turbo noise, with the delete elbow will sound just like stock.

well...come to think of it...if the delete elbow in place sounds like stock...what was the whole point in replacing the intake SILENCER?

You DO hear the turbo spool up more. I'm saying you can't really hear the factory bypass valve (barely). You should do it just to improve airflow in your intake system. I'm just saying the change in sound is not drastic, but yes, you can hear the turbo spool more.

to answer both commens, I hacked my friends snorkel up for him when I took it out. I cut it up, sealed the bottom to essentially make a U (elbow) to connect the ram air input and the airbox. Why did I do it this way? To retain the stock airflow and still keep cooler air coming into the airbox, instead of stagnant engine air.

To answer the question at hand, more spool and turbo whine were audible BUT the sound of the factory bpv didnt really change.

I have the GP Moto silencer delete elbow. Maybe I'm deaf but it sounds just like stock. I'm not hearing any turbo noises. I was hoping for something more...

I just ordered the Gp Moto delete elbow from Rallitek for more spool up sound. Are telling me you can't tell a difference after you installed it? If that's the case, I'll be fuming when it gets here! I'd like anyone else's comments too, if you have a GP moto elbow.

Hey if anything, the elbow saves you a few ounces of weight of the front end

Um, we sealed it with a thick plastic lid of some sort, just cut the plastic to shape and hot glue guned it until it was sealed right (might want to file down the elbow part so it is flat and you can seal it much easier that way).

The turbo sounds ..well..you can actually haer it lol. The BPV, isnt really supposed to make a sound, so you dont really hear it.

I added an mbc recently and now i can hear the spoolup at much lower rpms and its quite fun to hear. (when you get into higher rpms, the roar sometimes tends to overpower the wooosh)

Ya I just used the plastic from the silencer part of the box that I cut out. I cut it to fit, and then used plastic epoxy to seal it up. To the person above expecting much better spool etc, I wouldn't keep my hopes up. The difference is small, but it's a really cheap mod, and you can definitely hear spool up more.

the quick spoolup was a result of the mbc, not the silencer delete.

you can't really here the difference in 1st gear that much w/ the delete elbow you need ne in like 3rd or 4th just cruising and hit the gas. there is a sound difference though slight and i think it made me spool a tiny but quicker.

i would stick with oem filter. i was thinking of K&N, but from all the reasearch i have done here and at clubwrx i think i'll stay oem.
