Maybe if you have an electric car you could hack in and replace the space ship sounds with your preferred space ship sounds. Might be illegal though.

Replace your gasoline engine with a pair of ion engines

Just keep playing it on your stereo.

Is this an original idea or did you hear a car going wyeeeeeeaaaaaa and then decided that you wanted to do the same?

In any case, I commend your endeavour, good luck sir.

Just make mouth sounds.

TIE fighters fly around in space, space has no air, sound are vibrations of air, no air, no sound.

So if you can make your car completely quiet, then it sound like a TIE fighter.

But since that is impossible since you want to br driving around, you should duct tape some speakers to the roof and have a synth generate a continous TIE fighter tone, which would create the proper effect

I think the biggest obstacle would be from your perspective it would just be a steady annoying sound. TIEs only have their characteristic howl when doing a flyby. But if you're aware of that and you one want it for how it sounds as you drive by, I'd think just playing the tone through the speakers would do.

1. Buy an EV
2. Jailbreak the EV (good luck w this one)
3. Replace the boring OEM sound that is coming out of the speaker to warn pedestrians to a fucking epic Tie fighter sound.

Good luck and Godspeed.

Make it unobtrusive. Otherwise reconsider

I can’t speak to specifics but I can give you some ideas.

So the obd port might have some basic info such as acceleration and turns since and/or at least torque/thrust readings that you can poll since insurance companies and others have devices that use them to track your driving (often paired with GPS which you don’t need)

So some arduino project that lets you plug in and poll that data and to establish a trigger for some audio could be fun.

Pair that with something else that lets you connect via auxiliary or Bluetooth so you can play it over the speaker and you might have something.

This might be easier since a pi would be better suited to playback of audio and might be easier to get everything connected and to tinker with the Python to respond to certain readings

Bolt one end of some sheet metal to your bumper, leaving the other end to scrape along the ground. Should generate the required NYAAAUUUGGHHH sound wherever you go.

Whistles... They go woo woo?

You might be able to tune the radio to an AM frequency that picks up the engine interference.

Stick an elephant in the back

get a hole drilled in your tailpipe

It'd be all through intake, not exhaust. That's where you get all the sucky whoosh noises sound from. Anything from the exhaust will be too explosive. Effectively, harnessing the sound of air being dragged into the engine for combustion, not being banged out.

The original sound was inspired by the sirens attached to Stukas in WW2, the siren wailing as the plane dove and air rushed through. These were added simply to terrify people.

However, there is rotaries. Adding rotary blocks to a rotary engine will make a much smoother scream sound, like the V10s and V12s of earlier Formula 1 cars. Though, it will be lacking that open air sound. Maybe with the right exhaust and intake, a tone could be achieved.

If you went EV, electric motors are high-pitched unless very large. You could combine this sound with air vents—catching air like the Stukas' dive bomb air sirens—to get something similar, however, the air vents will be dependent on making noise with constant speed, disassociated with the engine. The TIE fighter also has no electric noise, it's all terrifying roar...well, whatever the inhaling version of a roar is.

Play slowed down African elephant noises on the stereo as you drive on wet roads.

Get yourself a Stuka Siren and modify it until the pitch is right.

40000 rpm wenkel engine with a muffler.

You mean like this guy?
