Alpha Series Mercedes-Benz 5.5L BiTurbo Downpipes
The Alpha Series Mercedes-Benz 5.5L BiTurbo Downpipes for your E63/CLS63 AMG are the ultimate solution for improving power, throttle response and exhaust note without sacrificing quality, fitment or design. If you are looking for the highest quality downpipes for your M157 engine, look no further!
Designed To Out Flow The Competition
Each Alpha BiTurbo Downpipe runs 3” (76mm) tubing for optimum flow all the way to your factory or aftermarket cat-back exhaust. Our competitors chose to mimic the factory passenger side piping where it necks down at the connection creating turbulence and hurting exhaust flow and power. This is a more cost effective way to make the system connect to the cat-back portion of the exhaust, but it hurts flow by creating a bottle neck. This was not a compromise we were willing to make so our engineering team implemented a ball-joint style connection retaining a full 3″ diameter maximizing your power gains. On our test vehicle 30HP and 35ft-lbs were seen on the catless version!
Unparalleled Fitment Through Proper Engineering
These BiTurbo downpipes aren’t something we quickly whipped up in a fabrication shop. These are properly designed and engineered using a CMM laser scanner for a perfect fit and space optimization. By choosing a 3 piece design we’ve provided improved adjustability and fitment making them easy to install. Placement of each O2 sensor bung was carefully chosen, eliminating the need to extend factory 02 sensor wiring. All brackets mount to their stock locations and each downpipe is routed in such a way that you DO NOT need to remove the factory heat shielding. All designed for a clean and proper OEM-like installation! When you choose our Alpha Series Downpipes, there is no need to hack up your prized possession.
The Difference Is In The Details
Another unique benefit is our GESi racing catalytic converter option. These 300 cell count units provide virtually no disruption in flow and feature a staked in design to hold the catalyst firmly in place. Many competitors offer a low quality converter option to keep the cost low and profits high. Often these units fail due to poor construction and inferior materials. When you choose Alpha you will remain emissions compliant and worry free for years to come.
