DescriptionThe whole story▼

Upgrade your Honda CBR 600 RR PC69 from a slip-on setup to a full race exhaust system with the Akrapovic stainless steel header E-H6R8/1. Engineered exclusively for track use, this 4-2-1 collector delivers a measured gain of 7.1 PS and 2.7 Nm while shaving a full kilogram from the stock exhaust mass — meaningful numbers at 14,000 RPM when every fraction counts.

Key Features

  • 4-2-1 full stainless steel (V4A) header construction, complete with all mounting hardware
  • Verified power increase of +7.1 PS at 14,000 RPM (stock 112.8 PS to 119.7 PS)
  • Torque gain of +2.7 Nm at 6,000 RPM for sharper mid-range response
  • Weight saving of 1.0 kg versus the standard header (8.9 kg stock down to 7.9 kg)
  • Direct-fit compatibility with the Akrapovic slip-on system S-H6SO17-HACT, converting it to a full system
  • Race-only designation — purpose-built for circuit use without compromise

Race-Grade Engineering

The E-H6R8/1 is machined and fabricated to Akrapovic's exacting racing standards. V4A austenitic stainless steel is selected for its resistance to the extreme thermal cycling of sustained track use, while the 4-2-1 collector geometry is tuned to exploit the CBR 600 RR's high-revving inline-four. Every weld, flange and collector junction meets the tolerances that Akrapovic's WorldSBK programme demands. The result is a header that pairs acoustically and mechanically with the S-H6SO17-HACT slip-on, completing a cohesive full system from airbox to silencer exit.

Track Performance & Setup Notes

Because this header moves the CBR 600 RR's exhaust characteristics substantially from stock, race mapping or dynamometer tuning is strongly recommended to realise the full performance benefit and protect the engine. The +7.1 PS figure quoted by Akrapovic was recorded at 14,000 RPM on a standardised test bench using the complete system; real-world gains will depend on mapping and ambient conditions. Plan accordingly when scheduling your track day preparation.

Fitment & Compatibility

This header is engineered specifically for the following application:

  • Honda CBR 600 RR PC69 — model years 2024, 2025, 2026
  • Designed to pair with Akrapovic slip-on S-H6SO17-HACT to form a complete exhaust system
