Closed mode
Quiets the sound and restricts exhaust flow. Handy when you want it quieter.
RED9
Quiet or loud, your call
With the RED9 exhaust valve you switch between quiet and loud when you want. We supply the system and weld it into your existing or custom exhaust.
Open or closed
Control your sound level
Closed for a quieter note. Open for full flow and more volume. One button, useful on track days and closed circuits.
Open mode
Full flow, as if no valve were in the line. More sound and flow for spirited riding.
What we do
Supply, welding and fitting
At Black Spark Performance you get RED9 from advice on diameter and material through to welding and finishing.
Sized to fit
The valve comes in three sizes and is internally matched to displacement. We check your line diameter so the valve fits.
Stainless or titanium
Choose steel/stainless or titanium to match your current exhaust material for a clean, strong joint.
Welding
We weld the valve into your exhaust, remove original valve systems where needed, and finish wiring and controls neatly.
Complete kit
Valve with actuator, remote and warranty card. Optional: button, bar mount and actuator finish in grey or titanium black.

Questions
Good to know
Stainless or titanium?
Match the valve material to your current exhaust. That keeps the joint strong, clean and heat-resistant.
Is my exhaust compatible?
Your line must be decatted so the valve can be welded in. Unsure? Send make, model and exhaust photos with your request and we will advise.
Which size do I need?
There are three sizes; the internal design is matched to displacement. We measure or confirm your line diameter before fitting.
How does installation work?
We weld in the RED9 valve, connect the controls and test open/closed. Allow about 1.5 hours, depending on the bike and exhaust.
Where may I use it?
This product is intended for race and track use / closed circuits, not homologated for public roads. See also our disclaimer.
Request a RED9 valve?
Send make, model, year and whether you want stainless or titanium. We come back with a proposal for supply and fitting.
