Default intake silencer deletes?

KAstle's is like 55+ shipping, Dynamispeed is 40$ shipped.

Considering a likely $20 price difference... what's the difference?

I have been wanting to get one a while now - just curious of anyone's opinions?

pssst....go to Ebay, very cheap. just make sure the one you buy allows you to bolt it up where the stock resonator does. it may not hold tight without it.

I think kastles is CF, but since its inside the fender it dosent matter.

I have the Dynamispeed one, fits like a glove.

PS: The CF one might be stonger...

If you get dissed on your threads, maybe you could show more respect on other threads, and not be so needy when you want a question answered.

Just that facts if you have any.

Just installed my Kastle tonight... Very nice..

HP Gains? I'm sure somone with a sensitive Butt Dyno will say yes. Check the bottom picture for what was removed, and you can only assume that it helps the airbox breath more.

But, mostly, it really helps tone up the intake sound. Then again, I have only had it installed for 2 hours...

rather than do a delete i removed the ram air all together. the coldest air is in the fender plus the ram air can get heat soaked. i bought a velocity stack from summit racing and modded it to fit. since your fairly local if you wanna check it out lemme know. itll save you a few $$$ and i think it makes the engine bay look a bit cleaner.

Yup, I did the same thing more or less. Removed the front scoop and replaced hole with fender plug (available from dealer). Bought a 2->4 inch rubber sanitation adaptor(home depot) and trimmed it a bit and stuck it in the stock box -> fender well. Works like a charm and really amplifies the intake noises.

I am sure the Kastle one is nice however seems unnecessarily expensive. I just picked up the one from Ashley at Dynamispeed last night and installed it today. This is the one and only mod I have on the car right now (Brand new car...Too busy with family stuff to do much else). The one from Dynamispeed is made out of a heat resistant plastic material (Sean said it was resistant to some crazy number) that seems about three times thicker than the stock snorkus. It is made by GP Motto. I got to meet Sean from GP Motto last night and talk to him about it. He was a great guy. The inside of the GP one is very smooth like glass. As far as strength differences between a CF one and the GP Motto one I think it would be like taking one elephant to crush it vs. taking two elephants to crush it. Make sense? I also don't see how the fender air could be any colder than the air from the intake duct however heat transfer from the engine makes some sense. Along the same lines though there is probably equal heat transfer through the fender liner from the brakes/tires/asphalt etc. Makes you think huh? I believe the WRX intake design is one of the better on stock cars.

The fit and finish is very nice on the GP Motto one. I plan to "redo" the mod and take pictures so I can write a nice instruction thread for everyone on scoobymods with pictures even a noob could figure out (including how to remove the jack from the trunk ).

The GP Motto one has the screw just like the factory snorkus and they supply you with a new screw and attachment spacer (however I am going to mod the GP Motto one to use the stock rubber spacer and write this up too as the rubber one will probably produce more quiet results if there is any vibration issues....too soon to tell).

Bottom line is this: Is it going to sound different with the elbow? NO. You will hear a tiny tiny tiny bit more whistle from the turbo (If you asked a girlfriend to see if there was a difference I doubt she could tell...No offense ladies...not something most girls are into) but that is it. I hear no more bypass sounds than I did with stock. The unit is very thick which leads me to believe that it absorbs the sound pretty well to be honest.

Now, is it going to change the characteristics of the car? Butt Dyno says the car feels like it has a tad more torque and feels more responsive to throttle. Don't expect a miracle but I say expect a bit of a smoother power that feels like it starts earlier than before. You may also see better results with an ECU reset (although I believe it will "learn" given long enough. I don't think mine has learned the part yet) To me it is the knowledge that I am not running my air all the way down and then back up to the air filter.



NOTES:
1. Remember that there is a nut that needs to be removed that is right behind the fog light (MY04). You have the one you can see when you remove the Intake Duct and then there is one on the snorkus toward the front of the car down lower. You can't remove the snorkus until you remove this PITA nut...Ask me how I know. I jacked the car up with the factory jack and removed three black fender liner fasteners and the clip. I also removed the fog light surround (pops right off) and then I could view the nut I had to remove more easily.
2. Although I don't foresee water being an issue in the elbow at all you may take the factory approach and drill a hole in the bottom of the elbow to drain any liquid that accumulates in the elbow due to scuba diving in your Scooby or possible condensation. This is probably not "necessary" as I believe the air box also has a hole in it for the same reason but since the elbow dips down you could keep a puddle of water there. Just an idea since the snorkus has a hole at the bottom.
3. You just removed ~1 pound from the car. The Motto one is lighter than the stock unit.
4. An aftermarket filter (K&N drop-in) may make the sound louder and improve the velocity of the air
5. I did not get a check engine light from installing this part (some say they do)

Jeez I have now written instructions and a review. I just get carried away. Let me know if you guys need more help and when life gets less hectic and I actually have a place to dump my photos off my camera I will do a "real" write-up on the GP Motto install. Ashley, maybe you can include it as instructions for the part as it did not come with any.

Another happy velocity stack owner. It does make more noise, but I like it.

dont want to thread jack, but this may help most who are donig intake silencer mod.

im thinking about doing that velocity stack mod, what do you guys think about leaving the ram air scoop in place along with using the velocity stack (taking out the silencer snorkus of course). i figure this, leaving the ram air scoop in the engine bay, you still get air from the front of the car to the fender, creating more positive pressure along with just having more air in the fender. or is there enough air in the fender that plugging up the hole would be better than having heat soaked air coming into the fender?

I feel like the "deletes" is what this thread is about so I feel sticking to that would be good lol.


I don't understand why people leave the intake breathing from the fender when the Elbows are cheap and you don't have to spend so much of your own time R&D. I know trips to home depot and making your own ghetto mod can be fun but the elbow for about 40 dollars is really worth it in terms of your own time to make something (Hours vs. Minutes). I know some of you guys want sound over performnance but I think the "delete elbows" are unmatched in performance as they give the air a fast travel path that keeps much of the stock design. A velocity stack sounds cool in theory but I doubt how much real world velocity you can actually add grabbing air from the fender like that. I think you have a better chance of grabbing nice cold air at the front of the car as the factory intended. CAIs (talking aftermarket) sound cool, they do, but for *most* cars the factory intake is more than plenty. In fact if you read most tuners recommendations they usually tune the best and most smooth results with the stock box and only even map for CAI because people are stupid enough to use them.

If your engine can't breath with the stock box because you have added so much modification that is one thing and may warrent a properly tuned CAI. Anyway that is just my .02


Let's get back to helping Chris decide about a "silencer delete elbow" as this was the original question.

There is so little to talk about...Get whatever one you want, like it makes a rats a$$ of difference when it comes to performance. I'm willing to bet the HP difference between a hacked snorkle, stock air box, velocity stack/ghetto mod and bling bling CF elbow is + or - 1.48271 HP.

What size velocity stack did you use?

Summit has only one with a 3in opening, but the diameter of the rounded opening is 7".

In the future, can you please refer to my elbow as "Uber Sudo JDM Bling CF Elbow..."

I did some real listening on my way home from the office tonight, and the Silencer delete does make an audible difference... Nothing major, but you can hear the turbo suck a bit better...

Default Yes, I can hear it.

I installed the GPMotto elbow a few months ago. Here in the north with the cold weather you can hear the turbo and re-circ valve, don't know about the warmer weather.
