I don't particularly like the sound of those Kreissieg exhausts. Makes the car sound like a cordless drill more than an F1 car. PRobably adds unnecessary exhaust weight too with all the extra tubing and solenoids. If I want to hear a true high rpm wail that will make your hair stand on end I'll go ride my R6 up to 15000 rpms, now there's a good race exhaust sound. And the whole bike probably costs less than those racer-boy exhausts!

this system with actuators sounds allot like something Porsche makes as an OE option on 996 and 997 cars.
Its called PSE and is basically an electronic muffler bypass.
Pretty simple to do

I have no cats, and just a GT muffler. The sound is quite subdued at low speeds, but it really bellows at higher revs. I generally drive to the bank on Saturday morning, to get cash for the salespeople's bonuses. One of them said the sound of my car makes him think of $100 bills!

Those headers were made by the Powerbroker, Tom Cloutier. His website is gone now :-( I remember it had some awesome sound clips! Now that was the best 928 I ever heard! He's worked with Louis Ott, so maybe Louis has some more info?

Mmmm........180 degree, equal length primaries........
Let's see......Lose everything after the primaries, route each primary to the individual tubes on the header/sidepipe collector.......heat shields for the brake and fuel lines......
(That's going to be a whole bunch of tubing----)
I think I'll work on the paint job some more before taking this on......

Mongo, the Kreissieg systems are very interesting- it appears that they are combining two separate exhaust paths with one being about 50% longer than the other...because sound travels at a given speed, you can then create a secondary pulse between the primary pulses by making adjustments to the length of path #2, if you see what I mean...sort of. So , on our cars, you would need the 180deg headers to start with, then, after the collector, split each side off with a Y, then from the Y into an X, then the solenoids, then back to the tailpipe AFTER the muffler, and then an H between the muffler tailpipe and the bypass tailpipe on each side, making sure that the bypass side is 50% longer than the muffled side..

Dude, you have side pipes, THOSE ARE WORTH LIKE 1 billion Horsepowers!
Trying to do this other stuff would only make your car more girly-manish! Dont do that, it should be tough and macho and full of awesomeness, only sidepipes can give you all that!
Actually, i think if you added smoke stacks, like your big-ol-rig, you could get into the 1.2 billion horsepower level. THAT WOULD BE AN UPGRADE! How bout like side pipes that go into smoke stacks? DUDE that would be awesome! DO IT! DO IT!

Makes a V-8 run as two 4 cylinder engines Ferrari is most notable (pun intended) as it sounds like a much higher RPM than it is. Normal V-8 has irregular firing order giving it the NASCAR sound
