Alpha Series Mercedes-Benz 5.5L BiTurbo Performance Exhaust System

The Alpha Series Mercedes-Benz 5.5L BiTurbo Performance Exhaust System was designed to give your E63/CLS63 an aggressive and sporty sound, boosting performance and enhancing your driving experience. This lightweight, stainless steel exhaust system offers you maximum efficiency without sacrificing the comfort you expect from your M157 powered AMG.

Unparalleled Performance And Fitment

Our Engineers designed this system using the latest in Computer Aided Design equipment resulting in maximum horsepower and excellent fitment. It features 3" (76mm) mandrel bent construction throughout and does not "neck down" like some other aftermarket systems. Each system is hand TIG welded and features an Alpha branded center brace which keeps your exhaust system firmly in place and let's others know you only accept the best for your AMG.

An Exhaust Note That is Music To Your Ears

This upgraded exhaust system stays mellow at cruising speeds for driver and passenger comfort but offers a deep rumble when you lean into the throttle. The droning sometimes associated with aftermarket exhaust systems, which can ruin the entire driving experience, was carefully tuned out. The end result is a perfect balanced sound for the ultimate performance sedan!





Let Your Turbos Breathe

By drastically reducing backpressure power gains of 30+HP can be seen on a nearly stock car. These numbers increase to well over 150+HP should you choose to upgrade into our Alpha 7 Performance Package and even further still with the Alpha 9 Turbo Upgrade Package down the road.

can you use the stock tips???? (i hope those are not the tips in the pic. lol. )

and is it any louder than stock when idle/cruising? if only somewhat? this is where im looking for the sound increase.

i admit om the video it sounds no different than stock to me, but videos dont usually do much to accurately represent.

I know in the "real world" mods don't just keep adding up IE not to expect peak gains from every individual modification that you, or ANY Co. offers for sale to keep adding peak #'s on top of each other as you install them. There's always a give & take to be expected, but just exactly what should one expect if say they added BOTH your Cat-Back exhaust system here (30 HP) & your soon to be released Carbon Fiber CAI system (you noted it's making 30 HP in preliminary testing)

So what should be expected when combining just these 2 mods to an otherwise STOCK E63 S AWD, 45-50 real world HP? & are your HP quotes @ the engine BHP for the obvious advertising advantages? Or are these Rear Wheel HP Dyno #'s? Thank you!

i dont get it, with the Alpha 7 Performance Package it states it makes 700 hp and 830 lbft torque, but then on your site it says your ECU tune alone makes 700 hp and 830 lbft.

am i missing something?

Looking at the various AMS threads, I'm also left wondering specifically where the power gains are coming from. Uncatted DP gets you 30, the carbon CAI gets you 30, the exhaust gets you 30. Not much information on where the power gains are being made either earlier in the curve or due to higher boost pressure thanks to the lower restriction. Just saying it makes it difficult to evaluate the products and also validate the claims with respect to less turbo lag, greater area under the curve, etc.

AMS_Performance

We need to update numbers. Our advertised numbers on the site are based on engine HP and the ALPHA 7 is really more of an ALPHA 7.5 or 750hp. We are estimating about a 15% drivetrain loss. Its probably a bit more with the AWD but a bit less with the RWD.

With just a tune we make about 600-620whp depending on the car.
The downpipes and full exhaust add about 30whp
The intake will add about another 30whp on top of that.

so an extra 60 whp = 70+ BHP gains after adding back DTL % these are crazy healthy super impressive figures, I'd love to see a Dyno backing this up, or better yet drop 1/4 ET over 1/2 a second & add 6+ mph in 1/4 trap speed

SilveRT8

As speed increases it takes more HP to lower your 1/4 time, so my guess would be a more realistic -.4 sec +4 mph, wich would still be very impressive.

AMS_Performance

SilverRT8 is spot on. Its not a flat calculation but we do have ever intention of backing all of this up on the track just like we always do!

Eric

mainly

so 750 hp is which? tune plus...?

im still confused...

Thericker

I was guestimating @ least 1/2 a sec or more in the 1/4 so I'm off 1/10 I'm certain you will back this up as your Co isn't the norm BS we see around here I'm very impressed w/ALL your modifications & am selling my V12 widebody she will be replaced w/most likely the CLS v8 biturbo '12-'13 or possibly the E63 I really have to test drive the E I already test drove the CLS 63 & loved it so we'll see.. Either way I'm going AMS all the way after purchase CAI/ECU/& turbo upgrades

Your mods are pricey but making 3X the power over Renntechs equally priced basically purely COSMETIC 10 hp CAI w/enlarged top only make the choice very simple

Here...someone (AMS) fill this out


|| CAI || DP(Cat) || DP(NoCat) || Full Exhaust ||

Stock | HP#A || HP#A1 || HP#A2 || HP#A3 ||

AMS Tune(1) | HP#B || HP#B1 || HP#B2 || HP#B3 ||

AMS Tune(2) | HP#C || HP#C1 || HP#C2 || HP#C3 ||

Tab formatting didn't stick for some reason but you get the point...

AMS_Performance

The CLS63 comes with tips, that image you see is the the E63 system which uses the tips that are integrated into the stock bumper.

It is mildly louder at idle and when cruising. I would watch that video as its pretty true to form.

Hi Eric,
Is this catback really bolt-on, with no cutting to the OE exhaust ?
Also when you mention that it's lightweight, can you tell how many pounds less than stock ?

AMS_Performance

No cutting whatsoever. I will get back to you on the weight savings. I wrote it down somewhere i just dont want to misquote you.

Eric

mainly

ok thanks

so what do the cls63 tips look like?

AMS_Performance

Honestly the stock tips look really good with the lines of the car so our tips are almost identical but with a larger internal diameter to improve airflow.

Eric

mainly

thats great have a pic?

SilveRT8

Any news on the weight savings for the catback alone compared to stock?
I'm a numbers guy.
Also what are the exhaust mods on the car in the video ?
Catback exhaust for sure, but did you also have the new downpipe, with or without cat ?

AMS_Performance

I will work on the weight numbers today for everyone. I am just going to re-weigh it all.

As far as the video that is our catback and high flow catted downpipes.

Edit: the stock catback on the 2014 is about 55lbs. Our system is 45lbs.

Will this exhaust work on 2014 E550 Sedan 4MATIC ???
