High-performance equal length Supersprint headers for Mercedes W204 / C204 C63 AMG 6.2 V8, for right-hand drive models (RHD) with catted Connecting pipes for the fitting of the Supersprint long tube headers with the Supersprint x-pipe centre section.
For Mercedes C204 and W204 C63 AMG, Black Series models included.
Manufactured in Aisi 304 stainless steel.
This component replaces the OEM headers, primary & secondary cats, and centre resonator with consistent power and torque increase thanks to the removal of any restriction to the gas flow while introducing high flow metallic cats.
The ECU reprogramming is compulsory to avoid the triggering of the Check Engine Light (CEL), connected to a "faulty catalytic converter" or "O2 sensor reading not correct" error.
The ECU tuning is recommended also to remove the throttle limiter which limits the power of the engine, present on the 456hp models.
The 4 into 1 collector uses the patented system with flanges, rings and springs, which allows free thermal expansions of the primary pipes without any mechanical stress,
The estimated power gain is +35 / +40 hp
