Intake Silencer Removal?

drdome99 · 03-13-2004, 06:06 AM

In doing some searching I noticed that a lot of older model WRX owners and even some 2004 WRX owners were removing their stock intake silencer for better sound and air flow. Is this something that can be done on an STi? Or has anyone done this and know if it actually does make for better air flow?

there is a thread with pics on how do de-install the silencer...it was one of the first mods i did myself...kinda easy...check it out and let me know if you have any more questions....check nasioc.com too

Last time I checked the thread on ClubWRX, Dan @ Godspeed had dynoed a stock STi @ 250 whp. 255 whp with IC spray. 258 whp without spray and after removing the silencer. I don't know about those numbers at all, but I trust the guys with the dynos. Removal is pretty simple and easy...when you get it out, you'll be amazed at how huge the silencer is.

oh yeah, it's really easy, and i would highly recommend the delete elbow from rallitek. it's $45.00 or so, and is a really nice fit. go for it...

skip the delete elbow...do the scoobymods cai....i have really good results and even jack at xx tuning was impressed....11.0-1 ratio....right where it should be...my two

Which one? There are a couple of them and are "homemade". Won't that void our warranties?

Oldal***uy, I dont see how slightly modifying the air intake would void a warranty....it just flows better,,,the computer will learn to deal...17500 miles no trouble yet...but the dealer would have you think that any mod you make will void,,,,such bs

The elbow at Rallitek is nice. Will not void warranty. You dealership service mechanics will never know it's there.

I second ,no wait third, the motion that the Rallitek elbow is the way to go. No voided warranty, no modifying the stock pieces, and can always go back stock if need be. easy mod! :P

i took out the ram air scoop and the resonator/snorkus.
went to home depot, purchased a 3" 90 DEGREE elbow.
fed it thru airbox and into fender.
cai w/ stock box
stock bypass valve is much more audible

i cant see how it can void anything since all your doin is removing a silencer...it does nothing but silence the air intake...find a new dealer...or better yet scrap the dealer find a good shop
