200TurboGT · 11-15-2009, 07:57 PM

hey guys i know theres a thread on this somwhere but i had a question to so i figured id make another one

i drove with my fliter cap lifted for a day or 2 (not sure if that was smart) but it gave me an unreal sound. so when i posted a thread to see if it was safe, i was told it could cause serious problems..soo whats the best way to get that same sound w/o it damaging the car..besides a bov

silencer delete?
k/n drop-in?

and how/where could i go about adding these parts to my car!?

thanks!

Do the silencer delete, and get a cone filter with a 3" neck. This will be loud. Just the cone filter alone with the silencer left in sounds good aswell. If you want to hear your motor don't even waste your money on a K&N drop in. It does not change the stock quietness, it just adds power. If you want even better sound and a bit of performance buy an intake. Lots of vendors on this site with great products. Just remember to return everything to stock before you take it in for service. There is a really good thread that tells you exactly how to do the silencer delete. Pictures and everything. Just look in the last few pages of threads in the 2.0t section. Or you could search it. Either way, that thread will help you alot.

i disagree politely

lol

i initially only had the silencer delete. received my k&n about 2 or 3 days later - not expecting any change in volume. but once i put in the drop-in filter the blow-off was much louder.

however i would assume the cone filter would be even better and at around the same price. i just chose the drop-in so i dont increase any heat-soak.

did u feel any power gain going from Silencer Delete to Silencer Delete w/ K&N Drop in?

You could always order it in a parts shop..

Cone filters for tuner shops are like selling gum and smokes for a convenience store, always in stock, and comes in any flavor you want...

Luujerr, you are correct. My bad. I just remembered that I did not start with a silencer delete and a drop in. I started with a cone filter, it sounded great but not loud enough. Then I did the silencer delete, and I'll never go back to stock. The only time my drop in gets slapped on is for service. Going from the cone and delete to just the drop in with the delete sounds like an overpowered sewing machine, imho. That's just my experience. I just figured if the op like the loud blow off he should not waste time with a drop in, because it's nowhere near as loud as having that mini silencer cap out. Luujerr is correct tho it does make it a bit louder, just not enough.

I have a qustion,

I accidently left my cone filter on taking it into the dealership, and the service guys not only told me, but stressed that i should definetly not be using this kind of filter because its way too much air, and it will quickly burn your headers???

i dont know much about how engines work so i didnt know what to think, but i havent put it back on since.....

is it really going to cause problems or are they just saying that because they are a dealership?

X2

K&N drop in lets you hear a little spooling, slight suction, and you can hear the stock bpv...

The silencer delete alone will do nothing to the sound of your car, unless you have super-human hearing. You have to do the silencer delete AND replace the stock airbox with a high-flow filter. Then it will be like night and day. I'm not sure about the drop-in filters, because I don't have experience with them. I'm assuming you will gain some sound there. But I'm also assuming you'll gain more sound with a conical filter, since there will be even more air going into the turbo. I have the conical filter, and it is very loud. Trust me, everyone around you will know you have a turbo under the hood.

IMO, the single best thing you can do for the 2.0T is get a high-flow air filter (and intake tube if you can afford it). It is a completely different driving experience. You will gain that sound we all want plus 5-10 HP, even with just a conical filter and intake tube that's sucking in hot air from the engine bay. You'll gain 10-15 HP if you have a heat shield or air box like the one made by cp-e that gets you some cooler air.

Intakes generaly do not do much for turbo cars. I guess I should say cold air intakes. You really should not worry a whole lot about iat as the turbo heats the air up anyway. That being said I do have a k&n typhon on my STi but it is strictly for the sound and it does have a heat sheild.

This is good info. Are you saying that putting a heat shield on that surrounds a conical filter or putting the conical filter in some kind of air box is not going to help over having the filter open to the hood because of the turbo heating up the air anyway?

I have switched back and forth multiple times now and I have to say that I feel absolutely no seat-of-the-pants difference in acceleration. I think a lot of time when you add something that makes the car louder (intake, exhaust, etc.) it tricks your brain into thinking you are moving a little faster.

Don't get an aftermarket intake filter and/or tube for HP gains, although a dyno might tell you that you'll gain 5 or 10 horses. You are not going to feel that. Get it for the sound. because, like I said, it's like a completely different driving experience.

i disagree. immediately after doin the intake silencer delete alone... i felt a difference

it felt like i was holding boost more in the higher RPMs.

NJGX03X87 · 11-17-2009, 10:35 AM

what size should the conical filter be to fit on the stock intake?

NJGX03X87 · 11-17-2009, 03:32 PM

My Goddd!!

i got curious after reading this thread, so i ran up to autozone and bought a $20 high flow filter. it sounds amazing! hands down pulls harder.

i thought after the silencer delete, thats as loud as it was gunna get. WRONG!

i almost regret just purchasing a SD BOV it sounds great without 1.

It might help but not enough to justify the cost. If you really want a heat sheild you can fab one up your self very cheaply. I think that the money could be better spent elsewhere or saved for a more expensive mod that will do something more than sound cool. ic,cat delete,flash,ect...

With that said I will say that it does give a lot better sound. Also these are just my opinions based on a lot of research and trial and error.

Has anyone tested the limits of the stock airbox on these cars yet? I know that the stocker on the sti is not a limiting factor until ~400whp or ~500chp.

Having a high flow filter on the 2.0T is like night and day from the factory air box, silencer on or deleted. Glad your curiosity got the best of you.

Thanks for the advice, and I do agree with you. What's your opinion on what material to use to make a heat shield cheap and efficient? Any ideas on how to go about making one? I thought about fabricating a heat box out of a sheet of stainless steel. I have no skills or tools to do any kind of welding, so I would need to wrap any seams with some sort of duct tape.
