Somebody is going to have to reference for me at what time in the video this car didn't sound very good. Just cos the video is sedate that doesn't mean the car is.

I think it sounds good
The tire noise masks the exhausts in the video
I like a sophistcated rumble and roar
Not a childish and obnoxious 'blatting', drone and painfully loud noise
To each their own: pull the cats and resonators to get loud

The 5.5 biturbo sounds great
So will the 4.0
This forum is peppered with folks who made exhaust modifications who are not happy with the results
More than a few have reverted back to oem or wish they could but have let go of the components or bought the car already modified
I bet a very small % of AMG owners mess with the exhaust
AMG pays a lot of attention the the sound, hence the distinctive sound and things like the 'sound room', etc
They have to tailor it for the majority of the market, not the extreme ends of the spectrum, some will say too loud, some not loud enough...can't satisfy everyone

Lol Tire noise masking exhaust sound? You kats aren't very familar w/Turbo apps... Turbos naturally muffle exhaust noises like a set of extra mufflers.. All this little gem needs is 3" straight pipes all way to tips, leave oem H-pipe, dump oem mufflers. It'll sound excellent NO droan or obnoxious notes..
Add 3" dwn pipes coupled to 300 cell Metal Cats for BEST aggressive/exotic melody yet tot civil (when not driving aggressively) & if you want to go more extreme? Ditch Cats completely you'll LOVE it
guarantee w/these simple mods you'd think it was a completely different beast..
Turbos hate back pressure so expect a nice bump in hp/tq + quicker thrtl response when running NO Cat versions..

Yes turbos dampen sound energy
But they also have waste gates
A turbo car without mucflers would be unbearable
With turbos you need less muffler, not no muffler, lol
They need to video like Audi: put a mic on the rear bumper
In this video wind and tire noise (from the AMG and recording car) overwhelmed the exhaust
Btw turbos work like shyte without some back-pressure
Response and drivability go to heck...this is a street car

proving my points you obviously know jack about turbos.. I have modded other turbos in the past and currently have a v12 biturbo w/all those mods you say wont work
I don't need to put on a clinic for you, wallow in your ignoranceMyriad of v12tt/v8tt/v4tt mercedes cars have the same or a slight variation of mods I listed they're proven to add hp/tq/throttle response & sound excellent
Your response was predictable & lightning fast... Truth be damned, you are never wrong lol..

Your professional opinion and engineering consultation is worth what it cost
Nothing
By following your advice the owner has not only destroyed the cars performance they have violated almost every federal and state emission and noise law, not to mention warranty
This engine is a 'system' and messing with only one sub-system upsets the whole thing, even more so with a complex turbo set-up
Btw lowering back pressure will not increase power
Boost or absolute manifold pressure is controlled by the ecu
The waste gates will dump more
Assuming your exh Q or mass flow is increased, it isn't, lol
The ecu regulates torque production which is proportional to Q
If predictable you should not have not poised what you did, hogwash
I may know zip about internal combustion power plant engineering but I know a bit more than you, and that ain't saying much

guess you missed this part of my post above, why don't you call the REAL TURBO engineers at Under Ground Racing and correct them w/your vast knowledge on turbos(who hold world records in 1/4 mi 1/2 mi & 1 mile races or and AMS, Heffner, etc etc etc who run Cat LESS on their HIGHEST hp/tq turbocharged apps..
???Turbos work like shtye w/out some back pressure??? Lol.. You ever see an Under Ground Racing tt Gallardo w/rear bumper removed? They only leave Cats on for guys that need SMOG cert, in their extreme 1500-2000 rwhp builds they ALL RUN CATLESS...

I trust the engineers at AMG over some half assed tuning shop that advocates illegal activity
Unless they show me a degree and license I wouldn't call them an engineer skippy
No need for insults and getting all constipated sugar britches
You said straight tubes no muffler
Removing the cats is illegal
Any tampering is illegal unless certified
Just because you spout buzz words does not denote comprehension
Like a parrot
I was studying turbos 30 years ago, actual formal training with physics and math not internet hyperbole...still work with them
I'm a certified turbo/injection tech by Deutz, look them up
What do you wallow in? Lol
As I said I may not know much but it is obvious I know more than you
Btw as long as the cat is up to design operating temp it's the chemisrty that determines efficiency not temperature, it's a chemical reaction it doesn't 'burn' the contaminants off lol
I have no dog in this fight
Who cares if someone buys a new w205 and ruins it by following your advice and hacking it up
I gave my opinion
You gave yours
Let the reader decide

Boy that new C63 really look like a E63 with a mix of CLA !lol!
Wait a week (with the Paris motor show) and we'll start seeing full reviews of that new AMG

So you don't trust ANYbody but AMG.. NO half assed tuning companies that advocates illegal activity ehh How bout Multi-Million dollar world renowned RENNtech (I mentioned them above, as offering NO or & hi flow cats on Turbocharged tuning applications, w/down pipes etc etc) http://www.renntechmercedes.com/www/about
Historically, RENNtech has been a prominent Mercedes-Benz specialist, and owner Feyhl himself is regarded by many as the USA's foremost authority on Mercedes tuning. His vast experience comes from his 12 years spent at AMG well before the tuning company became part of Mercedes-Benz in 1999, then going onto serve as that company's North American technical director prior to branching out on his own to start RENNtech.
RENNtech has begun to offer performance products for other marques specifically Porsche,Volkswagen/Audi, BMW and Bentley vehicles. The product offerings focus on RENNtech's core competencies such as performance engine tuning, suspension, exhaust and custom fabrication.RENNtech is an authorized Akrapovic exhaust dealer and also the exclusive North & South American distributor for Aixro rotary race engines. Our Aixro race engines also power the worlds fastest and exclusive racing karts, the RENNtech SLR kart, which is built in house by RENNtech.RENNtech designs, engineers and manufacturers their proprietary line of tuning products in-house atour facility which features a full fabrication and machine shop with CNC and rapid prototype capabilities;an in house performance dyno, complete engine management and software tuning capabilities; acomplete service/repair/installation facility and a full time design, engineering and sales staff.Our headquarter facility is located just north of the Palm Beach's in Lake Park, Florida.
