I don't know how different the '15 is. The 2010s have only one foam at the end of the tube connecting to the cabin. The 11-14s have two foams. I didn't need any tools on mine. Well, just my phone flashlight. Just manually pull the hose and took the foam out and just pushed it back in. Took me 3 minutes.
Lol the foam just sits in the end .. Almost falls out. Unless there is more foam in the boxes and chambers.
Riiiiigghhtt... because Mustang owners are notorious for not caring what their car sounds like :doh:
I think in your first question you are asking how you can make the sound of the turbo louder. The best way to do that is with a downpipe and blow off valve. For your second question, it is very easy to make your car loud, just get more aggressive mufflers or an aggressive catback. Electric cutouts are also an option. However, it will never sound like a muscle car in the way that a GT does. Some mufflers/catbacks have a deeper sound than others, though, so look into that.
Because it is a somewhat artificial way of gently suggesting to you, the driver, that your car has more power than it would have had if the sound tube had not been fitted. Not as bad/fake as playing a sound track through the audio system, but there's still some deception going on when what you're getting is only what sounds like more power.
I don't think they put the tube in to trick you into thinking the car has more power than it really does. If they stripped out the sound deadening to allow you to hear the engine better, would people label it as a type of trick? They just know that people who buy sporty cars usually like a sporty sound, and in the process of building a car with a relatively hushed and refined interior, they needed a way to pipe a little attitude back in. So they did it. Nobody accuses the dual-mode exhaust on a Camaro of existing to trick owners into thinking their car has more power than it does, it just exists because people like hearing powerful engines. I think I know what you mean when you call it "artificial", but it really isn't. Its purely mechanical and the sounds originate from the engine's actually activity, as you probably know. Some Porsches and other sports cars use similar equipment. I think this approach is much better approach than the Ecoboost's speaker-based exhaust noises, which are truly and completely artificial, as you mentioned. The completely artificial speaker-based sounds are what I consider unacceptable.
So maybe they refined the interior just a bit too much. Less sound deadening is a performance mod no matter what kind of hard driving you do (less weight, right?).
I'll give you "fewer people" on the Camaro's NPP exhaust, but they do exist. Count the folks who trick it into always being in the 'loud' mode among them (it's a really simple trick). The Maxima in my sig used to have a similar but purely mechanical dual-mode exhaust, that wasn't even noticeable by anybody I know of who rode in that car.
It's not as real as the comparable trick used by some back in the carburetor days (flipping the air cleaner lid over to open up the air cleaner assembly for more air in - and more sound out as a by-product.
IOW, at least as far up the pony/sports/muscle car enthusiast scale as entry-level driving enthusiast, people have become just as spoiled as the mainstream sedan buyer. A shame when you stop to think about it.
Remove it. Simple as that. Is a removable piece that many people enjoy leaving in place worth posting a complaint over on the internet? I don't think so.
No matter how intertwined you try and make sound and power, they are not that hard to separate and people still enjoy the engine sound in a sporty car. I just don't see your point. People like to hear that engine. Period. Regardless of its relation to power, there is nothing wrong with enjoying the sound of an engine.If you ever step into the gas just to hear the engine roar, and think for only a moment that "hey, I think this car might be fast", being fooled is exactly what's going on.
The carb trick added a little power, or at least it did before the OE's started ducting intake air from outside the (hot) engine compartment. The sound tube adds 0 HP and 0 torque. See any difference here? If I want to have (or have to have) more intake sound, there'd better be a little more power coming along with it, otherwise it's just another gimmick. Function (for the driving part) over form, if you please.
Mustang needn't be setting their sights on out-Lexusing Lexus here . . .
Yeah, I could easily live with far less refinement than even what my '08 has, do so without sacrificing any of its use-ability, and I'd still enjoy the car just as much. Then again, under the right weather conditions I could jump into '32 hotrod or a Caterham 7 and go most anywhere without thinking twice. As long as I didn't have to cart much stuff, anyway. Maybe this picture ↓↓↓ will put my perspective for "people have become spoiled" across a little better. That's not me driving, but I've ridden in that car under the conditions pictured.
