Termignoni GP-Classic Slip-On Kit for Yamaha YZF-R6 (2006-2026) – Carbon & Stainless, Race Use Only

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.

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 (K08909430I) 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. Note that the silencer can only be fitted in conjunction with link pipe Y11709430I — ordering the silencer without the link pipe is only appropriate when you already have the pipe in hand.

Fitment & Compatibility

This kit fits the Yamaha YZF-R6 manufactured between 2006 and 2026. The silencer alone (SO0509440ICI) requires link pipe Y11709430I to mount correctly. No road-legal fitment is supported — this product is designed solely for closed circuit racing and must not be used on public roads.
