DescriptionThe whole story

Rooted in Akrapovic's racing heritage and finished to the exacting standards that have made the brand synonymous with performance exhaust systems, this stainless steel header transforms a slip-on setup into a full exhaust system on the Yamaha YZF-R6. The precision-engineered 4-2-1 collector design is crafted from V4A stainless steel, delivering an unmistakable acoustic character alongside genuine gains in power and torque across the entire rev range.

Key Features

  • 4-2-1 full stainless steel header (V4A grade) supplied complete with all fitting hardware
  • Compatible with Akrapovic Carbon slip-on silencers for a refined sporting note and with Akrapovic Titanium slip-on silencers for an intense racing sound
  • Also compatible with Akrapovic standard (OEM replacement) silencers
  • Optimised collector geometry improves flow for increased power and torque throughout the rev range
  • For closed-circuit competition use only — not road-legal
  • ECU remapping recommended to extract maximum performance and protect engine longevity

Design and Finish

The header carries the hallmarks of Akrapovic's manufacturing philosophy: clean weld beads, consistent tube geometry and a polished stainless finish that ages gracefully under race conditions. Unlike aftermarket headers that treat finish as an afterthought, every section of the E-Y6R5 reflects the same attention to detail found on the full Evolution and Racing Line systems. It is a component that looks as purposeful mounted beneath a YZF-R6 fairing as it does on the workshop bench.

Performance and Sound

The 4-2-1 configuration is the result of Akrapovic's development work on the YZF-R6 platform across multiple racing seasons. By pairing this header with either a Carbon or Titanium Akrapovic slip-on silencer, riders unlock a sound profile and performance character that a slip-on alone cannot achieve. The mid-range torque benefit is particularly noticeable on the R6's high-revving inline-four, making corner exits noticeably more responsive. ECU remapping is strongly recommended to ensure fuelling is matched to the improved exhaust flow.

Fitment and Compatibility

Designed and developed specifically for the Yamaha YZF-R6 from 2008 through to 2026. Compatible with the full range of Akrapovic slip-on silencers for the YZF-R6, including Carbon and Titanium variants, as well as Akrapovic standard silencers. This header is intended exclusively for track and competition use and carries no road-use approval.
