DescriptionThe whole story▼
Shedding 3.2 kg over the standard exhaust — from 6.6 kg down to just 3.4 kg — the Spark Exhaust WSSP2022 Replica full system is one of the most rewarding daily upgrades you can bolt to a Kawasaki Ninja 400. Whether you commute through the week and hit the track at weekends, this Italian-made titanium system delivers sharper throttle response, a genuinely race-inspired soundtrack and a weight saving that the chassis notices immediately.
Key Features
- Full titanium header and Spark Force slip-on silencer with titanium end cap — exceptional heat resistance and long-term durability with minimal mass.
- Weight reduction of 3.2 kg (stock 6.6 kg reduced to 3.4 kg) improves handling balance and acceleration feel from the first ride.
- Removable dB killer lets you run a measured 102 dB at 5,500 rpm on track days while keeping noise within acceptable limits on the road — one tool, two characters.
- Designed to clear original fairings and radiators, so fitment is straightforward without bodywork modifications.
- All exhaust springs and the complete mounting hardware are included — nothing extra to source before installation.
- Handcrafted in Italy to Spark's motorsport production standards, the same brand trusted in World Supersport competition.
Built for the Street, Inspired by the WSSP
The WSSP2022 Replica name is not marketing shorthand — it traces its geometry and material specification directly to Spark's World Supersport programme. For Ninja 400 riders, that translates into a system that genuinely improves everyday rideability: the titanium header flows exhaust gases more efficiently than the heavy stock unit, filling in mid-range torque and making the 400 cc parallel-twin feel more responsive in normal traffic conditions. The titanium silencer keeps temperatures under control even in slow urban riding, and the angled outlet delivers a deep, purposeful note without the antisocial bark that makes some aftermarket cans impractical for road use.
Track-Day Versatility
Remove the dB killer — supplied in the box — and the character shifts noticeably. At 5,500 rpm the system registers approximately 102 dB, satisfying most closed-circuit noise limits while letting the engine breathe more freely at high revs. Reinstalling the dB killer takes moments, so the transition between road and track configuration is something you can manage in the paddock without specialist tools. To unlock the full performance potential, Spark and Inter-Pace both recommend pairing this system with a purpose-built race map or a rolling-road remap.

This system is engineered specifically for the Kawasaki Ninja 400 across the full production run from 2018 to 2023. It is designed to be compatible with the standard Kawasaki fairings and radiators, requiring no cutting or modification. Part number GKA8827.
