DescriptionThe whole story▼

Same titanium manifold, one difference that decides how the silencer is carried: on this version the bracket is welded to the link pipe. The exhaust supports itself rather than hanging off the chassis, which is the arrangement that lets the S1000RR keep its passenger footpegs.

Key Features

  • Titanium 4-into-1 manifold with the silencer bracket welded onto the link pipe.
  • The silencer is carried by the exhaust itself, not by a chassis hanger.
  • This is the arrangement used in the Grid-O system, the one version that allows passenger footpegs.
  • Accepts Spark's Konix Evo, Force Evo and Grid-O silencer groups.
  • Supplied as a manifold only.
  • Hand-welded in Mantova, Italy.

Build Quality & Materials

The welded-on bracket is a small detail with a large consequence. Hanging the silencer from the link pipe removes the need for a chassis mount, which frees the subframe and — on the S1000RR — leaves the pillion peg mounts usable. It also means the manifold carries the silencer's mass and vibration, which is why Spark builds this joint rather than bolting an adapter on afterwards.

Everything else matches the bracketless GBM8821R: titanium tube, TIG welds, couplings machined from bar, geometry taken from Spark's championship programme.

Performance & Sound

Identical gas path to the bracketless version, so identical behaviour. The decibel figure comes from the silencer: 104 dB with the Force Evo, 107 dB with the Konix Evo, 114 dB with the Grid-O — all measured by Spark without a dB killer.

Fitment & Compatibility

BMW S1000RR (2019-2026), M1000RR and M1000R. Two questions decide which of Spark's four manifolds you want: titanium or stainless, and bracket or no bracket. This one answers titanium and bracket. If the bike already wears a race subframe with a chassis hanger, the bracket is redundant weight — take GBM8821R instead.

Road Approval

None. This is a competition manifold, sold without approval and without a catalytic converter.
