Cracked hit the nail on the head on some of these:

cracked said:
Cars have come a long way since the days when they ran on four hooves and were called "horses." Since then, we've innovated the electric motor, fuel injection and decorative rubber scrotums. What could possibly be left?
Unfortunately, as you'll soon find out, quite a bit. A whole lot of computerized wizardry is coming to your car, and some of it will make your life a living hell.

The Innovation:
For every new technology, there's some busybody utterly terrified it'll commit mass murder. There were probably people campaigning against the dangerous, untested Segway. So leave it to these safety advocates to insist that hybrids, with their wussy quiet engines, need to have some sort of warning sound to alert pedestrians and blind people when they're coming.
Really? Are we crazy, or do regular cars not make all that much noise right now? It's not like everybody's growling down the street in a Harley these days.
How It'll Ruin Your Life:
The "warning sound," as it turns out, isn't going to stop with a fake "vroom." Oh, no, that would be far too limiting in a world where everybody has replaced their cell phone ring with T-Pain. People need to express themselves. So, you'll get cars like the DiMora Natalia, which has an MP3-enabled horn. Yes, the day has arrived when you can toot some Lady GaGa at the guy who just cut you off. Take that, shiny happy person!
Of course, this needlessly complicates the primary function of the horn: Warning people you're about to kill. In a few years, driving on the highway will mean you're being subjected to, at best, hipsters blasting classic Simpsons sound bites at you, and at worst, sixty year-olds trying to warn you they're about to plow into you at 100 MPH IF YOU DON'T GET THE berkeley OUT OF THE WAY by inadvertently pressing the button that plays a Kenny G sax solo that was engineered by 80s music producers to be the opposite of alarming. We're almost certain you're not allowed into heaven if the last thing you hear before dying is "Songbird."

Uh huh... and I'll raise that with my big, gas-guzzling, whomping american V8 with Borla pipes and headers.

I'll see your big, gas-guzzling, whomping american V8 with borla pipes and headers, and raise you two more (one with flowmasters and one with a magnaflow).
Okay, time to put an exhaust cutout on a rotary.

I think I've heard that guy at Thunderhill. From the paddock, you couldn't not hear him, and it was impossible to hold any conversation as he went down the back strait.

I'll stick with my straight piped fire shooting turbo 4.

I'll see you your exhaust cut out and raise you a rotary at 7500 turns on headers alone. I tried that several years ago and I think my ears are still ringing. 
Or even better yet, no headers. Did that too and singed the paint on the inner fender.
I can't imagine why my wife bitches about me being deaf. 
I lit the Jensenator's 13B off for the first time with headers and a 3" diameter straight pipe about 6' long. It sounded wicked but I believe the neighbors' windows are still vibrating. And they are still cursing me. Oh wait, they do that anyway...

We ran the Mighty Dak's engine with no headers, just for fun. Surprised our ears weren't bleeding. It was cool.

No. This was an FB or FC RX-7. Don't know who owned it. I've never heard any particularly quiet rotory cars at the track, but whoever this guy was, he was easily the loudest thing I've heard at the track. Ever. I don't know how he wasn't black flagged immediately.

Next time your up there, I'd talk to Bob if he's working... if it wasn't his, I bet he does know who owns it. That man is the god of rotaries.

my Grandfather had (among many others) a favorite saying...: this one was "first lier doesn't stand a chance"... see what happened when I was first to post about a straight pipe...

I remember running a Porsche type 4 engine without an exhaust at all bolted to the heads... that lasted all of 30 seconds
Between the Harleys and the 20v AE92's angry bumblebee theme, I'm covered. But I bet the LS400 makes as much noise as a Prius. Humm. May have to put some cutouts in the headers on that to save pedestrians. I bet that 1uzfe would sound pretty mean with some open headders.

I'm going to put a cutout on the MGB. Janel has informed me that the Camaro's Borla exhaust just barely reaches minimum sound levels. But none of my other cars make more noise than they have to make. Although the Seven does blow flames.

My old type four powered beetle would blow flames when accelerating.. and would pop and crackle on overrun.. I never knew until my dad drove it and i followed in his car.. then I figured out why nobody followed that closely behind

That information is usually directly behind her yelling "HEY DEAF GUY
