Mercedes-Benz 5.5L BiTurbo Alpha Series Performance Exhaust System

The Mercedes-Benz 5.5L BiTurbo Alpha Series 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.
