And why you should leave it on, at least on a stock Mustang, and pull the baffle out of the firewall end of the tube.

My car, all stock, still has the stock mufflers, just the baffle taken out of the sound tube.

Makes for a pretty good interior sound at WOT, at least I think it does.

 

The video doesn't even do it justice! I took mine out this morning and couldn't believe the difference. I may even put the baffle back in once I get the new exhaust for fear that it will be too loud inside the car.

 

There are two foam baffles, one right behind the diaphragm-looking part and one on the end of the tube at the firewall. I tried pulling both out and found the noise a bit too 'harsh'. I found that pulling just the baffle on the firewall side is perfect.

 

baffles shnaffles. Put a real exhaust on that car and let everyone hear how good it sounds

 

This is like saying that it's a good thing M3's pipe engine noise through the speakers and you should never remove the fuse that controls is. Come on.

 

Yes, exactly, sound is a little ragged with both baffles removed, removing only the one at the firewall is just right.

That way it only sounds off when you put your foot in the throttle.

 

Maybe it is, maybe not, don't know anything about a m3.

Porcshe has a engine sound transmitting device on the new 911 Turbo too.

It really just amazes me how harsh some peoples feelings are about such a simple deal like this.

I like the sound it pipes in and so do a lot of others although they may be afraid to admit it for fear of all the ridicule they hear over it.

 

Maybe they are afraid, wouldn't it just make more sense to get a better exhaust for that good sound instead of something that seems a little synthetic?

 

Doing that too.

 

I know what you're saying but it's not synthetic... it's the actual sound of the engine but with the superior cabin insulation in cars these days you don't get to hear them anymore. Plus it's already there vs. a $400 - $700 axle back exhaust system. My '66 GT is super loud inside and out. It's just a little metal box so you can't help but hear the engine. And everything else...

 

But it is coming off the intake, how can that be the "noise" of the engine if it comes straight off the intake?

 

?? Intake is part of the engine... More to "engine" noise than exhaust. In fact, the reason different engines have different exhaust notes (e.g. small block vs big block modular vs pushrod and different car makes) is that the engine itself through it's design has it's own unique sound. The exhaust is just the exit point for said sound.

 

Obviously intake is part of the engine, but you don't get noise from the neck of a flute of the mouth piece of a trumpet, the sound comes out the back, exhaust.

 

Apples to oranges. Once again, exhaust is just the exit point. The engine has it's own unique sound for many reasons as mentioned before. To spare beating a dead horse, if the intake portion of the engine makes no sound, where is that noise in the sound tube coming from...?

 

Well, at least for the flute, you are wrong. The sound from a flute comes from the air passing over the mouthpiece. Have you never seen someone playing a flute? They blow air across the mouthpiece opening.

And there is plenty of sound coming from where the air goes into the engine.

The attitudes toward this simple sound transmitting tube just boggles my mind, SHEESH!!!

 

Turbulent air, I wouldn't know. And to say that exhaust is just the exit point can't be right. Yes internals make a difference, volume of the engine, OHC or CIB, but all the harmonics, or most of it is going to leave through the exhaust.

 

Maybe you're right, I didn't think about the fact that sound is created at the mouth piece and then augments through the pipe. Still seems like the sound from the tube wouldn't be true to the actual sound of the motor. It's more for the sake of argument with my stance on the sound tube. Though it does get in the way of the dip stick which is annoying.

 

Correct, it exits through the exhaust. You can put the exact same exhaust system on two different types of engine and they won't sound the same with the exhaust being the constant. Hence (for my point at least) it's not the exhaust that is generating the unique sound, it's the specific engine. That's all I meant. Put dumps on one car and factory exhaust on another with the same engine and they will also sound different... Only because the exit is now different.

You may not believe me or agree. That's ok too.

 

I was just getting at listening to the intake shouldn't, in my mind, sound similar to the engine's actual sound.

 

Umm becuase this is free and takes 2 minutes?
