Spark Exhaust Konix Evo Slip-On Silencer Titanium – Aprilia RSV4 / RSV4 RR / 1100 Factory (2021-2026) GAP0402

Shedding 3.7 kg from the tail of your Aprilia RSV4 transforms how the bike moves beneath you — the Spark Exhaust Konix Evo Slip-On delivers exactly that, dropping the silencer weight from 5.3 kg down to just 1.6 kg through a hand-crafted titanium canister finished with a carbon end-cap. Produced in Italy and engineered for riders who refuse to compromise between road usability and track-day aggression, this is one of the most accomplished slip-ons available for the 2021-2026 RSV4 platform.

Key Features

• Significant weight saving of 3.7 kg (5.3 kg stock reduced to just 1.6 kg), improving chassis dynamics and responsiveness throughout every corner.
• Titanium canister construction offers exceptional heat resistance and long-term durability without adding unnecessary mass.
• Carbon end-cap gives a purposeful, race-inspired finish while contributing to overall structural rigidity.
• Removable dB-killer allows a straightforward switch between road-legal use (approx. 104 dB at 5,500 rpm) and full track mode (approx. 107 dB at 5,500 rpm).
• Optimised exhaust flow enhances throttle response and mid-to-top-end performance across the RSV4's rev range.
• Made in Italy — hand-assembled with all exhaust springs and the complete fitting kit included in the box.

Craftsmanship and Performance

Spark Exhaust builds every Konix Evo by hand at their Italian facility, and the attention to detail is immediately apparent. The titanium body is precision-formed to resist the sustained high temperatures generated by the RSV4's V4 engine, while remaining lighter than any comparable stainless steel alternative. The carbon end-cap is not decorative trimming — it is a structural component that reinforces the outlet and withstands the thermal cycling that destroys lesser materials over time.

The removable dB-killer is the defining practical feature of this system. Pull it out before a track day and you gain the full, unfiltered voice of the Konix Evo at approximately 107 dB; refit it for the road and the output settles to approximately 104 dB at 5,500 rpm — a meaningful reduction that keeps the exhaust usable daily without blunting the character. Both figures are measured at 5,500 rpm and represent the kind of transparent engineering that serious riders appreciate.

Road and Track Use

The Konix Evo's 3.7 kg reduction is not merely a specification talking point. On a motorcycle as agile as the RSV4, removing mass from the rear end alters the chassis balance in a way that is felt immediately — the bike turns in more keenly, holds lines with less effort and flicks between directions with noticeably less inertia. For track-day use, Spark Exhaust recommend pairing this slip-on with a dedicated race mapping or a dyno session to extract the full performance benefit. On the road, the improved throttle response alone makes the upgrade worthwhile.

Fitment and Compatibility

This slip-on silencer is a direct, bolt-on replacement designed specifically for the following models:
