Spark Exhaust Grid-O Full Titanium Complete Exhaust System – Aprilia RS 660 (2020-2026) GAP8808T

The Spark Exhaust Grid-O full titanium complete exhaust system transforms the Aprilia RS 660 into a sharper, lighter machine — and unlike pure race-only systems, it arrives ready for road use too. With a 3.0 kg weight saving over the stock unit, a removable db-killer, and a pillion footpeg bracket included as standard, this is the rare full system that earns its keep on weekend rides just as readily as it does on circuit.

Key Features

• Full titanium construction — header and GRID-O slip-on silencer — for a genuine 3.0 kg weight reduction (from 6.1 kg down to 3.1 kg), sharpening chassis response and reducing unsprung mass.
• Aggressive, race-bred soundtrack of approximately 107 dB at 5,500 rpm without the db-killer — the same specification used on Moto2 and Superbike World Championship circuits.
• Removable db-killer (part number G9980) included in the box, allowing you to dial back the sound level for road riding or noise-regulated trackdays without purchasing extra parts.
• Pillion footpeg bracket supplied as standard, meaning the RS 660 retains its road-legal configuration straight out of the box — no hunting for additional hardware.
• All exhaust springs and a complete fitting kit are included, so installation is straightforward with no additional purchases required.
• Handcrafted in Italy — the precision and finish quality associated with Italian performance manufacturing.

Everyday Usability

What sets the Grid-O apart from outright race-only hardware is the practical thought behind its packaging. The db-killer ships inside the box, ready to fit whenever you need to comply with noise limits at a trackday or simply prefer a more measured exhaust note on an early morning run. Swap it out in minutes and the full 107 dB race character is restored. The included pillion footpeg bracket means your RS 660 stays fully road-configured without any compromise — a detail that matters if the bike does double duty between commuting and weekend circuits.

Performance & Build

Titanium is the material of choice for race teams precisely because it combines a very high strength-to-weight ratio with outstanding heat resistance — qualities that translate directly to longer service life and consistent performance across a full race distance. The GRID-O silencer design feeds directly from Spark's involvement with professional championship machinery, where unrestricted performance is non-negotiable. The full-system approach — replacing both header and silencer — delivers optimised gas flow from the exhaust ports through to the outlet, which is why Spark recommends pairing the system with a dedicated race map or a dyno session to extract every last gain from the new flow characteristics.

Fitment & Compatibility

This complete exhaust system is a direct-fit replacement for the following model:

• Aprilia RS 660 — model years 2020, 2021, 2022, 2023, 2024, 2025, 2026

The chassis bracket is listed as an optional accessory, allowing the system to be configured for pure track use without the additional hardware if preferred.
