DescriptionThe whole story▼
Built without compromise for the track, the Termignoni GP-Classic slip-on kit transforms the Yamaha YZF-R6 into a sharper, faster, more responsive race machine. Combining a carbon fibre and stainless steel silencer with a precision stainless steel link pipe, this kit delivers measurably improved throttle response and a weight saving that every lap time will reward.
Part numbers, current Termignoni 2025 price list: Y117094SO05 is the complete kit — GP-Classic slip-on silencer and the matching link pipe under a single part number, nothing else required. SO0509440ICI is the silencer on its own; it still needs link pipe Y11709430I, which is not included and is ordered separately. Both options are designed exclusively for closed-circuit racing on the Yamaha YZF-R6 and are not approved for road use.
Key Features
- Race-tuned exhaust kit engineered specifically for the Yamaha YZF-R6 across the full 2006–2026 model range.
- Carbon fibre and stainless steel GP-Classic silencer reduces unsprung mass while projecting an aggressive, purposeful track aesthetic.
- Stainless steel link pipe (part number Y11709430I) ensures corrosion-resistant, long-service durability under sustained racing conditions.
- Optimised exhaust routing improves scavenging and throttle response at mid-range and top-end rpm.
- DB-Killer included — fit it to comply with circuit noise limits, remove it when the regulations allow.
- Race use only — not road legal, designed exclusively for closed circuit competition.
Performance on Track
Termignoni has supplied exhaust systems to the WorldSBK and WorldSSP paddock for decades, and the GP-Classic carries that pedigree directly to club racers and trackday enthusiasts. The silencer canister pairs carbon fibre's exceptional stiffness-to-weight ratio with a stainless steel core, channelling exhaust gases through a geometry that prioritises mid-range punch and top-end breathing. The result is sharper pick-up out of slow corners and a stronger pull to the rev limiter — exactly what the R6's high-revving inline-four rewards.
Build Quality & Materials
The GP-Classic silencer (part number Y117094SO05) uses a carbon fibre outer shell over a stainless steel body — a construction that withstands the thermal cycles of back-to-back sessions without delaminating or discolouring. The stainless steel link pipe (Y11709430I) mates precisely to the R6's existing downpipes and forms a sealed, vibration-resistant joint. Every component is finished to Termignoni's race-shop standard, with no excess material and no unnecessary hardware.
The kit is available as the complete slip-on and link pipe combination, or as the slip-on silencer alone.
Fitment & Compatibility
This kit fits the Yamaha YZF-R6 manufactured between 2006 and 2026. No road-legal fitment is supported — this product is designed solely for closed circuit racing and must not be used on public roads.
