Full Exhaust System FMF PowerCore 4 — Yamaha TT-R 90, TT-R 90 E 2000–2003, with spark arrestor (4T)

The FMF PowerCore 4 is a four-stroke silencer — the sensible choice when you want more power and less weight without going to the most expensive line. Elliptical aluminium canister with cross-weave internal packing for long life and even sound damping. Better exhaust evacuation means higher flow and more power. A removable spark arrestor is usually included. Fits: Yamaha TT-R 90 (2000–2003); Yamaha TT-R 90 E (2004–2007). Specifications — material: Aluminum, Stainless Steel, configuration: Single Canister, weight: 1,41 kg. Note: does not meet the 2025 FIM sound limit — intended for practice and closed courses, not for FIM-sanctioned racing. Delivery 5–8 working days. SKU: 040080.
