Spark Exhaust Moto GP Full Titanium Racing System Suzuki GSX-R 1000 / R (2017-2026) GSU8807T

Spark lists code GSU8806 in two materials. GSU8806T has a stainless collector. This is the other one: titanium from the cylinder head back, and 714 euro more for the change.

Key Features

• Full titanium racing system for the Suzuki GSX-R 1000 and GSX-R 1000 R, 2017 onwards.
• Titanium collector in place of the AISI 304 stainless one.
• Moto GP silencer in titanium — Spark's racing and extreme option.
• 110 dB at 5.000 rpm, 115 dB at 7.000 rpm.
• Fits with the original fairings, footpegs and radiator.
• No road approval — closed-circuit use only.

Where the Money Goes

A four-into-one collector for a litre superbike is a large piece of pipework, and building it in titanium rather than stainless changes the cost of the system more than any other single decision. Titanium has to be shielded from air on both sides of every weld, it springs back when it is bent, and a forming mistake cannot be recovered.

What you get for it is weight and heat behaviour. Titanium is roughly forty per cent lighter for the same strength and holds its shape through the temperature cycling that eventually distorts thin-wall steel.

A Note on the Published Weight

Spark quotes 4,0 kg against a standard 10,4 kg for code GSU8806 as a whole. That figure covers the code, not each material version separately, and a titanium collector is necessarily lighter than a stainless one. Spark states no separate number for this build, so neither do we — the direction, though, is not in question.

The photography works the same way: Spark publishes one image set for the code, and what differs between the two builds is the collector material.

The Silencer Is Unchanged

Moto GP: short, wide, titanium, and the loudest option Spark offers on this motorcycle. 110 dB at 5.000 rpm and 115 at 7.000, exactly as on the stainless-collector build. Spark describes it as racing and extreme and does not soften that.

Standard Bodywork

Compatible with the original footpegs, fairings and radiator, in Spark's own words. The system that requires racing bodywork is the separate 2019 evolution for tuned engines, not this one.

Track Use Only

Spark lists this build as not approved. No certificate, no catalytic converter, and a decibel figure that rules out road use anyway. It must not be fitted to a motorcycle ridden on public roads.

Fitment & Compatibility

Suzuki GSX-R 1000 and GSX-R 1000 R, 2017 onwards. The stainless-collector build of the same code is GSU8806T at 1.655 euro. The full titanium system with a Konix Evo silencer is GSU8809T at the same 2.369 euro.

Road Approval

None. Spark lists this system as not approved; it is built for closed-circuit use and must not be fitted to a motorcycle ridden on public roads.
