    No CEL's, the silencer is located before the MAF sensor, and before the air filter. You will get the same amount of air needed, and it's argued that you get cooler air since it draws air from the wheel liner. The only drawback to this mod is the air filter will get dirtier quicker. But not enough for it to be a huge bother.

    If you like a louder Turbo spool at high RPM, then this mod is good. If you like a quiet commuter, then don't. Also, a owner of a WRX, with stock WRX turbo did this mod after seeing the video. He commented that even the WRX turbo spool gets a lot louder as well.

    Cool! Yeah there are ways to patch the hole. You can either tape it, or ppl have been using fiber glass. However, be warned, you'll have to poke a hole after filling the hole anyways. The hole is used to keep water from pooling up and sucked up. When you remove the silencer, u will see a hole at the bottom of the silencer as well. I just left it open, it's fine, no problems =)

    Hahahaha, yeah, that's the thing about videos, I can't show it in real time, you guys will be bored to death. It took me about 45 minutes to an hour as well. So if this is your first time modding, you did it in an amazing quick time lol.

    Well? How does it sound? You notice a difference? =O

    Hmm... do you drive an STI? or WRX? If you don't hear it, i'm assuming you are driving a WRX, or you aren't pushing the STI hard enough =p. On the STI, it's very apparent when you shift at 3-4k RPM, from first to fourth gear. =P

    hi thats a great video. i was wondering if the same mod can be made to my 1999 wrx? i only had the car 2 weeks and before it did have a hks induction kit, but since putting the standard box but on theres no chattering. will deleting the resonator make the chattering again? The reason i taken off the hks is that i heard it can damaged the maf is this true?

    thank you

    I don't think removing the resonator will cause any chattering... At least, I've never heard of anyone complaining about any chattering. As for the HKS damaging the MAF sensor, I'm not too sure about. I've never heard of an induction kit damaging the MAF sensor. However, if you change your intake, it's most likely that you need a tune to accompany it. For both STi and WRX, it's known that you wouldn't need an intake unless you go with a larger turbo and more boost. Again, I can't say for sure that it damages the MAF sensor, but it's probably better that you went back to the standard intake. =) Hope this helps.
