So here is my current setup so that it provides context:

1) Kleeman catless downpipes and tune

2) Deleted Resonator

3) X-Pipe

4) Brabus Exhaust

Without the Brabus exhaust, the sound with the #s 1-3 (videos have been previously posted), was pretty impressive. It was very throaty on startup and would only get more so once I got on it a little. With this setup, the car is a whole new animal. Why you ask (you didnt ask)? I'll explain.

First, with the ability to electronically control whether the valves are open or closed, the car (in mine and some others opinion) can sound pretty close to a stock CLS63 on startup (valves closed) or like a beast (but not a "shotgun blast" beast) when the valves are open. Second, with modifications #1-3, I feel like the Brabus exhaust better focuses the sound emanating from the car, and makes it much more of a "controlled angry".

As someone who is not as technical as many others on here, I would compare the before and after to this: Before, the car's sound was akin to a brutal fighter with a very wild, unorthodox, eye popping style. Now, the sound is like a well trained killer who has a deadly, but controlled technique and can kill on command -- meaning, that even with the valves open, the car doesnt attract the attention of police and what not unless I want it to. Before, the more "untamed sound" was loud all the time (but not necessarily a bad loud, but still loud).

The install at ACG (especially with techs like Assan and Wes) was fantastic. Those guys are masters of their craft and I cant stop smiling. Here are some quick videos I took at Street Noyz (my stereo place) right after they fixed my loose door handle and loose tweeter. The videos are short because I had to jet to work.


Valves Closed



Valves Open

Sounds wicked homie! Can't wait to hear it in person soon!

so the brabus exhausts connects up to only the X-pipe right?

Pertplus

Thanks! Will try to get some in and post them up!

Thanks Big Boy! Hopefully you can come out when I am up in LA!

Pertplus

I believe that is correct. All bolt on, and nothing needs to be welded.

Of what I could hear from the short clips this sounds sick. I would describe it more refined and exotic. Although many like the throaty v8 sound I always thought the recent amg engines sounded like trucks. The new m157 is cleaner but been waiting for a good exhaust to clean it up. I'm not interested in paying brabus tax but applaud you for a sick setup

Pertplus

Thanks, I'm going to post better clips when I'm not time constrained.

Very cool- can't get the videos to work but I'll try again on another computer.

How do you control the valves? Is it linked to the steering wheel button? (sorry if this is answered in the video(s))

Pertplus

There is a button in the mini consol next to the shifter and also if you press and hold "up" on the steering wheel it will open the valves and if you press "down" it will close them.

Thank you. Also just viewed the videos. Sounds awesome!

Is the switch OEMish looking?

Sounds amazing!!!!! Great choice on exhaust system

Pertplus

The switch is a button and is in the console that you can open and close...and no it's not OEM looking. But because it doesnt have to be visible, it's especially not an issue for me.
