Here is a video of how the exhaust setup looks from underneath.
Here is a short video of startup and rev. Going to take some better revs this weekend and some drive-bys.

Sounds amazing, great job! There's just one thing that really bugs me: The exhaust tips. The bumper has a factory cutout for only one exhaust tip on each side, and the tips you have just looks very out of place. Are you at least planning to get bigger cutouts on the bumper to accommodate for the quad exhaust? I would still just go with the factory dual tips, it just looks the best in my opinion.
Also, have you decided on going back to true duals, or are you going to keep the Y-pipes?

The stock tips appealed to me until I realized how it was just a piece covering the actual muffler tip. That's why I wanted a different one.
Yeah I'm going to try to make it into true duals soon. I still think true duals are higher pitched.
When I change it back to true duals and remove y pipe I might change the tips.

Does that work on the non-turbos? The TTs limit the throttle position or fueling or something to cap the RPMs in Park/neutral. It definitely sounds different and doesn't rev very high as compared to loading it in gear (good way to break cv shafts, lol) or actually driving. I'm not sure what the control mechanism is exactly, as they don't hit a traditional spark rev-limiter like most cars...it just flatlines and holds around 4000 or so, I think it's probably a throttle blade position limit.

Do you know the mechanism for it though? It doesn't sound/feel like the typical ignition cut/cylinder drop limiter. I'm guessing it's the electronic throttle body ignoring pedal input and being closed to maintain RPM.

My 350Z would just close the throttles a little at 158mph on the stock speed limiter like you took your foot off the gas, and it was such as strange feeling, like the pedal stopped working. On that car you could set different limits to use throttle, fuel and spark. By default the throttle does everything, once I got into tuning it and tried the spark cut limiter I got good proper machine-gun noises from the catless exhaust on the limiter. Much better

That's how almost all factory rev limiters work on electronic throttle cars now. It's very boring by comparison lol.

Took it on the highway today. So far here are my observations.
1. The car idle is actually very quiet. It's actually quiet under 1500rpm.
2. The sound really comes out between 2-3k rpm
3. Past 4k it becomes more throaty than that high pitched F1 sound.
4. There is some high drone going from 1.5k to 2k rpm on lower gears.
Other than that it's pretty good so far. I'm still going to be looking for ways and researching how to make it sound higher pitched before I consider the custom headers.

Electric throttles must be quite expensive, but from memory, there's a dozen clever things you can do with one unit. See if I can remember:
- Rev limiter
- Speed limiter
- Cruise control
- Traction control
- Boost control
- PAS load compensation
- AC load compensation
- ABC load compensation
- Drive load compensation
- Gear shift smoothing
- Idle speed control
- Cold start fast idle
- Anti-bunnyhopping (yes, that's a real thing)
- Low gear re-mapping
- Oversize throttle?
- Throttle position sensing maybe?
- Integrated kick-down switch maybe?
Low-gear re-mapping is a LandRover feature that slows down throttle opening when you're in a crawler gear, to help avoid snatching.
Oversize throttle is my idea. Big throttles give more power at high revs, but they can compromise torque at low revs. Therefore use a throttle map that doesn't allow full throttle until you reach half revs, or something like that.
Some of those things you can do with idle by-pass valve or ignition retard, but not all of them.

I have another video with my friend recording while driving next to me. I haven't heard my car from without being a driver. I also have some more videos with a dash cam recording how it sounds from the inside. Will put them up soon.

Holy crap that's amazing. To be completely honest though, my car doesn't sound too far off at those high rpms! I might just take a fly by of my car to compare it with yours! We are basically running the same setup (nothing after the primary cats) and have the same car except for the two turbos. This should be interesting! I'll have the video up soon.

I am now convinced that this v12 the the best sounding engine Mercedes has came up with. I wonder why many exhaust companies doesn't make high pitched mufflers/resonators for the m137 engines. I know that if some one these exhaust companies like Capristo, Armytrix, Kreisseg, make just mufflers like they do for the Ferraris, this car will sound like the F1 without the manifolds.
I am actually going to contact Armytrix and see if I can convince them to design an exhaust system using the same techniques they use on their Ferrari exhaust. Take a look at the picture of the Ferrari 599 GTO exhaust. That muffler design can almost fit into the S600.

What was your rpm during the fly by ? I heard your car shift and you slowed down for the curve ahead
To replicate the Japanese videos manually put your car in first and leave it there , then you don't have to go so fast . Remember the f1 beastly sound only comes out fully right before the rev limiter !! When it up shifts you'll lose the sound

But yeah on lower rpm is where the sweet spot is. I will show that on the other video with my friend recording while next to me.

Front page news!
Great stuff! Thought the front page crowd would think so too...

It really hits that sweet spot right before the shift point. I don't if I prefer that or the S8 with Milltek exhaust. Both have a very exotic exhaust tone for such unsuspecting cars. The looks you must get!
