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 in the system. This is 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 cat-less version!





Unparalleled Fitment Through Proper Engineering

The 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. We also took the time to integrate the factory O2 sensors, heat shielding and brackets for a clean and proper OEM-like installation. When you chose Alpha 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 nearly 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.

They look Great!!! Any word on the carbon air boxes? Id probably like both as an upgrade when I pull the trigger.

 

nice product but no offence almost 3k for it?? MBH same exact thing 1k less I don't see how it could be such a big difference. but anyways

 

MB tax even worse under 0bama I see...

 

Our pipes are not the exact same. We have a three piece V-band design which is critical because when moving to our turbo outlet pipes in the future you will be able to swap out that top section and have a full 3" system with no reducer at all. with our pipes you can also swap between catted and non catted by changing that top pipe only. Our pipe is about $700 more which I think is worth it for that option.

So Turbo outlet pipes are on the way?? Then Iguess the system woule be similar to Weistec.

 

Turbo outlet pipes are indeed on the way but we wanted to develop a pipe for people that didn't want to go through the arduous task of dropping the engine to swap the turbo outlet pipes. We also didn't want to ask people that wanted to do that to buy a whole new set of downpipes. This was a nice compromise without sacrificing any performance.
