Spark Exhaust De-Cat Racing Collector Stainless Yamaha Ténéré 700 / World Raid (2019-2026) GYA8504

The catalyst on a Ténéré 700 sits in the collector, and it accounts for most of the 3,4 kg that assembly weighs. Spark's replacement is a bare AISI 304 stainless manifold at 1,7 kg — half the mass, no catalytic converter, and no road approval.

Key Features

• De-cat racing collector in AISI 304 stainless steel.
• 1,7 kg against 3,4 kg for the standard collector.
• 96 dB at 4500 rpm measured together with the GYA1601 Dakar silencer.
• Works with the Spark Dakar silencer or with the original silencer.
• Compatible with the centre stand and with side bags.
• Racing part — not approved for road use.

What Leaves With the Catalyst

A catalytic converter is a ceramic brick in a steel shell, and both are heavy. Taking it out of the Ténéré's collector removes 1,7 kg from a point low and central on the motorcycle, and it removes the restriction the brick puts in the gas path.

What it also removes is the emissions control the bike was type-approved with. That is the trade, and it is not reversible in the eyes of an inspector — this article is sold as a racing part and Spark lists it as not approved.

Euro5 and Euro5+ Are Not the Same Job

This is the part worth reading twice, because the two generations of Ténéré need different treatment.

On Euro5 machines, the manifold can be fitted without remapping. To keep the lambda sensor connected in its new position you need the extension cable, article 0CAVO003 — Spark states this as necessary, not optional.

On Euro5+ machines, remapping is required. The bike will run without it, but not correctly, and Spark says so plainly rather than leaving it to the fitter to discover.

96 dB, and What That Figure Covers

Spark quotes 96 dB at 4500 rpm for the combination of this manifold with the GYA1601 Dakar silencer. It is a measurement of that pairing, not of the manifold alone and not of any other combination.

The comparative bench runs behind Spark's published curves were made without touching the original ECU, so the figures describe the hardware rather than a tune.

It Also Works With the Standard Silencer

Spark builds this manifold to pair either with one of its own Dakar silencers, making a complete kit, or with the silencer the motorcycle came with. The second option is the cheaper route to the weight saving and the freer gas path, and it leaves the back of the bike looking untouched.

It is still an unapproved part either way. Removing a catalyst does not become legal because the silencer is original.

Fitment & Compatibility

Yamaha Ténéré 700 and Ténéré 700 World Raid, 2019 to 2026. Pairs with the Dakar slip-ons GYA1601TOM, GYA1601DOM, GYA1602TOM and GYA1602DOM. On Euro5 machines order the lambda extension cable 0CAVO003 alongside it. Remapping is required on Euro5+ machines.

Road Approval

None. Spark lists this collector as not approved. Closed course and off-road use only — fitting it to a road-registered motorcycle removes the catalyst the bike was type-approved with.
