Spark GRID-O + titanium collector Full LineRef : SPK0208 / SPGYA8875T

Manufacturer reference: GYA8875T — Spark Grid-O / Step 3 (Full system), competition exhaust system.

This complete Spark system represents the ultimate evolution (Step 3) developed specifically for the track. Constantly refined in competition, it is particularly famous for achieving a top speed of 275.5 km/h at the Mugello circuit in the Italian championship. It replaces the entire heavy original exhaust system of the Japanese supersport to maximize the performance of tuned engines. This system is exclusively for closed circuit use and does not have road approval.

• Finish: Full Titanium (racing collectors in titanium with CNC machined joints + Grid-O silencer in titanium).

• Compatible models: Yamaha YZF-R6 (2007-2024).

• Specificity: "Step 3" architecture with increased collector diameters, featuring CNC machined joints for optimal reliability. The installation is compatible with the original fairings but requires the removal of the passenger footpegs.

• Approval: not approved (designed to meet the noise limits of European championships such as CIV)

• Weight: 3.4 kg (a massive weight saving of -6.9 kg compared to the 10.3 kg of the complete original system).

• Soundproofing: dB killer not included (sold separately).

On the track, this complete system pushes the dynamic limits of the Yamaha YZF-R6. Unlike the versions equipped with the Force silencer, this variant opts for the ultra-compact Grid-O. Spark's R&D department has meticulously calculated the sizing of the pipes to ensure optimal gas evacuation at very high revs. The record weight saving of nearly 7 kg drastically lightens the machine, significantly enhancing the bike's agility during quick angle changes and heavy braking.

(Note: Installing this complete racing titanium system requires an ECU reprogramming to optimize the air/fuel ratio, ensure engine reliability, and exploit its full potential).
