Saw the sickest SL 55 AMG ever!

Saw the sickest SL 55 AMG ever! Was walking around Boston on my lunch break today and heard a loud blower whine coming down the street (washington street for those that know boston). I turn expecting to see an 03-04 blown cobra or something along those lines and I see this SICK SL 55 AMG. Didnt have a chance to talk to him as he was driving by but he had a real nice sounding exhaust as well, def not stock and was pretty damn loud. My question is are the factory blowers on these AMG's as easy to upgrade as the one on the cobras (pulley swap) or do you think it was an aftermarket blower (if one exists)? I was really impressed as I havent see/heard a modded SL55/E55/S55 AMG before and this one was amazing!

This is taken driectly from their website:
AMG 5.5L V-8 SOHC SMPI 24 valve intercooled supercharger engine
Engine liters
This number represents the total volume, in litres, that is displaced as the pistons move inside the engine.
SOHC valvetrain
The single overhead camshaft (SOHC) which opens and closes the intake and exhaust valves is located over the cylinders, directly operating the valvetrain. This construction is highly efficient, with fewer moving parts, than the common pushrod design in which the camshaft is in the crankcase and actuates the valves with pushrods and rocker arms. It also makes multiple intake and exhaust valves practical.
Overhead cam engines are more efficient and powerful than most engines of comparable size. Overhead cam engines developed out of racing technology. They easily operate at higher RPM and develop more horsepower than older engine designs. They are typically more efficient and responsive than pushrod engines.
Intercooled supercharger
The intercooler is a heat exchanger that lowers induction temperatures of a supercharged engine, creating a denser air charge for more efficient combustion and more power.
An intercooler increases the power and efficiency of a supercharged engine. It also helps reduce wear and tear on the engine from a continuously overheated air charge. Intercooling enhances the function of supercharging. It also helps minimize long-term wear and tear that might be exacerbated by a continuously overheated air charge.
V-8
V8 engine design uses two banks of 4 cylinders in a V configuration.
V8 engines are powerful and operate smoothly. V8 engines typically develop more torque, provide better low-speed acceleration and operate more quietly than other engines with comparable horsepower.
Sequential multi-port electronic fuel injection
Sequential multi-port electronic fuel injection delivers fuel in precisely timed pulses corresponding to the opening of each intake valve.
This EFI system provides more precise combustion for better performance and improved fuel economy, as well as excellent driveability and cleaner emissions. Sequential port injection is an advanced form of electronic fuel injection that offers performance and efficiency advantages over other EFI systems.
Valves Per Cylinder
The number of valves, both intake and exhaust, that allow fuel and exhaust to move in and out of each cylinder.
Premium unleaded fuel
Premium (91 pump octane or higher) unleaded gasoline is required.
Premium octane permits the engine to run at peak performance and efficiency.
It is def supercharged as Ive seen a few before at car shows with their hoods open and def a factory supercharger on them, but they were very quiet, and this one was extremely loud (well loud enough for me to hear it coming plenty far away). Just wondering if anyone knows if a smaller pulley will make these louder like that or if it is an aftermarket blower?

the blowers are quiet as hell, even with pulley upgrade. there is one local to me with the pulley upgrade and you couldn't even tell it was supercharged. im thinking it probably had aftermarket blower.

yea ive seen some of their cars in magazines, brabus does a nice job but I wish they had a sound clip somewhere of their blower setups. Im gonna have to find this car again and ask the guy what he has done because it was such a sick car...
