The Alpha Performance Mercedes-Benz M133 2.0L AMG Cast Downpipe
The Alpha Mercedes-Benz M133 AMG Cast Downpipes are the best performing and most durable on the market! During testing our shop CLA with our Alpha M133 2.0L AMG Downpipe, Filter, and Alpha M133 Tune our Engine Calibrators saw amazing gains across the power band in both wheel horsepower and torque! The power came on earlier and carried over 100 ft lbs of torque gains from 2900rpm to 4850rpm!!! Turbo spool-up was significantly improved! The long gradual transitions within the cast down pipe section allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system!
First in Class Durability and Performance From Proper Engineering
Our downpipes perform better and are not prone to cracking like the alternatives offered by the competition. The Alpha Performance CLA45/GLA45/A45 AMG Downpipes feature 4mm thick cast stainless steel upper and lower section to retain as much heat in the down pipe as possible. The competition’s versions have many welded seams which are prone to failure.
By casting these downpipes in robust 304 Stainless Steel we were not limited by the design restraints of hand fabricated construction. The AMS Engineering team utilized Solidworks (3D software) to blueprint the inlet and outlets with smooth features and geometry to optimize exhaust flow. They then 3D printed the down pipe to ensure an OEM level of fitment before casting the very first article!
An Unmistakable Alpha Exhaust Note
The Alpha Performance CLA45/GLA45/A45 AMG Downpipes offer a more pronounced, throaty exhaust note under wide open throttle yet are subtle at idle and while cruising. It’s a perfectly balanced sound for the ultimate, all around, supercar!
The Difference Is In The Details
Another unique benefit is our motorsports catalytic converter option. These GESI brand 300 cell count Ultra High Output (UHO) units provide virtually no disruption in flow providing emissions control with no notable loss in horsepower. For durability these converters feature a staked in design to hold the catalyst cores 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 Performance, you will remain worry-free for years to come.
