Spools like a different car
Backpressure gone. Boost comes in a full 400rpm sooner and it pulls all the way to redline now. Fitment was dead-on — no massaging, no fighting the O2 bungs.

The details
We are excited to offer AMG enthusiasts a highly cost-effective path to unlocking the true potential of their M156-powered W204 C63. The Flowsport Series Heatshield Long Tube Headers, complete with a matching mid-section, deliver massive performance upgrades and a menacing exhaust note. Designed as an accessible alternative to our flagship USA-made MBH systems, this complete package provides incredible power gains alongside advanced thermal protection for your engine bay.
Heat is the enemy of performance. To combat this, these durable stainless steel headers are fully encapsulated in a premium thermal heatshield wrap. This specialized layer drastically lowers under-hood temperatures, protecting vital surrounding engine components and preventing power-robbing heat soak during aggressive driving. By eliminating the highly restrictive factory exhaust manifolds and optimizing exhaust scavenging, this complete bolt-on system reliably generates an impressive 35 to 40 wheel horsepower (WHP) increase.
We stand behind the Flowsport series with a robust 5-year limited warranty. If the headers experience defects or cracking within the first year, we will repair or replace them. For the remainder of the warranty period, we will attempt repairs to keep your system performing flawlessly (please see our policy page for full details). Please note: While these popular systems sell out quickly, we constantly have new inventory arriving to keep backorder lead times to an absolute minimum.
