Dyno-Comp AMG 63 Series M157 BiTurbo Downpipes

One of the biggest performance gains on the new Mercedes Bi-Turbo engine comes from replacing the cars factory downpipes. Dyno-Comp offers downpipes made with American 304 stainless steel and manufactured in the USA! Through extensive R&D along with proven dyno restults we have seen massive gains in both horsepower and torque across the board.

It is highly recommended that these downpipes be installed with our stage-2 performance package which utilizes an ECU reflash to replace the cars factory calibration. This ensures not only greater horsepower increases but also the saftey of the vehicle.

Dyno-Comp/MBH "Super Long-Tube Headers" W220 S55 AMG

Dyno-Comp continues to produce our long tube headers for your Mercedes! After months of C.A.D. design and testing, these NEW S55 long tube headers use the same design and material as all of our other world renowned Dyno-Comp/MBH AMG headers. All of our Dyno-Comp headers are MADE IN THE USA with American steel!!!
The horsepower gains are HUGE over the stock “log” manifolds, and crushing competitor "shorty" Chinese made headers.
The Dyno-Comp AMG-S55 Long Tube headers are guaranteed to make a minimum of a 40-45 wheel horsepower gains. When used in conjunction with Dyno-Comp stage 3 software ECU and Pulley upgrade Dyno-Comp has seen 80 to 100 Wheel HP, and with many tests seeing even greater power gains!
Key Features:
- “True” sequential firing order design
- 1.75” 321 stainless steel primary pipes
- 321 ½” thick stainless steel flanges
- Pre and post cat O2 sensor bungs
- Left and Right test pipes included
- Bottom: 3” header flange to test-pipe adaptors included.
-One piece “mono-flange” design ensures a positive exhaust manifold seal. (other competitor headers relief cut the flash resulting in warped flanges and poor seal.)
- TIG welded, with full back purge, and built by hand by our master fabricator. This is the same craftsmanship and quality of materials that goes into INDY car headers made by the same hands which make all of our Dyno-Comp AMG-63 and AMG-55 headers.

Dyno-Comp/MBH Long Tube Tri-Y S63 Headers

- 2.0” Primary pipe design. (all other competitor headers only use 1-7/8”) “True” sequential firing order design. This results in cylinder “scavenging” which improves engine efficiency by utilizing the velocity of each exhaust stroke in order to draw fresh air into each cylinder ready for the next combustion cycle. 
- “Try-Y” design. Specifically for the normally aspirated 63-AMG engine, this “Try-Y” header design further optimizes scavenging effect which dramatically increases top end power while optimizing low to mid range torque. 
- One piece “mono-flange” design ensures a positive exhaust manifold seal. (other competitor headers relief cut the flash resulting in warped flanges and poor seal.)
- 304 stainless steel 2.0” primary header pipes with 321 stainless flanges.
- Pre and post cat O2 sensor bungs Includes all new gaskets and additional installation hardware
All of our Dyno-Comp headers are MADE IN THE USA with American steel!!! The horsepower gains are HUGE over the stock “log” manifolds, and crushing competitor "shorty" Chinese made headers. Our Dyno-Comp 63-AMG and AMG-55 headers are made with the BEST craftsmanship and quality of materials possible, and they are TIG welded and constructed with the same "hands" that goes into building INDY car headers!!!

RESULTS:   +35-40 HP Gains!!!
