Spark Exhaust Grid-O Euro5+ Full System Low Mount Triumph Street Triple 765 (2023-2026) GTR8824TOM

Road legal, and the same silencer that won the 2020 Moto2 world championship. Spark's Euro5+ homologated full system for the Street Triple 765 MY23-26 removes three point seven kilos, keeps a catalytic converter, and needs no ECU work — a rare combination on a naked bike of this size.

Key Features

• Euro5+ homologated full system for the Triumph Street Triple 765 R, RS and S, 2023 to 2026.
• 5.9 kg against 9.6 kg standard — 3.7 kg saved.
• Grid-O silencer, low mounting: full titanium, visible TIG welding, titanium grid.
• AISI 304 collectors with CNC-machined connections and compensators.
• 3-in-1 pipe with a special catalytic converter — racing cells, rich noble-metal impregnation.
• Dual lambda sensor setup, with a plug supplied for single-sensor bikes.

Why It Had to Be a Full System

Spark explains the change directly: on the MY23-26 Street Triple the original exhaust is a single piece. There is no joint to cut into, so a homologated Spark kit for this bike cannot be a slip-on or a 3/4 system — it has to replace everything from the cylinder head back.

That is why this product exists alongside the modular kits Spark still sells for the earlier bikes, and why it costs what it does. You are buying collectors, the catalysed 3-in-1 pipe, the pre-silencer box and the silencer as one homologated assembly.

A Catalytic Converter Worth Having

The interesting engineering here is the catalyst, not the silencer. Spark builds a special converter into the 3-in-1 pipe, and describes it as very different from other aftermarket parts: racing cell count, and a strong impregnation with noble metals. Spark calls it a genuinely precious component, and it is — the metal loading is where the money goes.

The point of spending it is that the system clears the Euro5+ gas limits and improves performance at the same time, without touching the ECU. A cheap catalyst does one of those things. Doing both is what separates a homologated exhaust from a restricted one.

Two Lambda Sensors, One Part Number

All of Spark's homologated kits for this bike carry a dual lambda sensor arrangement, because the latest Euro5+ machines run two. If your Street Triple has only one, a plug for the second boss is in the box.

It is a small detail that saves a real problem: a spare sensor boss left open is an air leak into the exhaust stream and an error light on the dash.

Fitment & Compatibility

Triumph Street Triple 765 R, RS and S, 2023 through 2026. The same system with the black ceramic-treated box is GTR8824BOM. The lateral-mount versions are GTR8825TOM with the Grid-O and GTR8826TOM with the Konix Evo. The catalysed 3-in-1 pipe as a spare part is SGTR8824*02.

Road Approval

Euro5+ homologated. Legal for road use with the catalytic converter fitted, and no ECU modification is required.
