About CARBON SMITH
CarbonSmith — Carbon Speed Stacks for the GSXR1000R
Inside your bike's airbox sits a small part most riders never think about: speed stacks — short tubes that direct air immediately before it enters the throttle bodies. Their exact shape and length genuinely determine how air moves in that final moment before combustion.
CarbonSmith builds a carbon fiber version of this part, engineered specifically for the GSXR1000R.
What Are Speed Stacks, and What Do They Actually Do?
Speed stacks (also known as velocity stacks or air horns) are short tubes that sit inside the airbox, directly above each throttle body's intake opening. Their job: regulating airflow and increasing its velocity before it enters the engine, improving the density of air present at the moment of combustion.
The precise shape and length of these stacks genuinely affects the torque curve across different RPM ranges — this isn't a cosmetic detail, it's a real piece of engineering that shapes how an engine actually performs.
Why Carbon Fiber Specifically?
The original version of this part is typically made from plastic or lightweight metal. Switching to carbon fiber delivers two genuine benefits:
-
Reduced weight — every gram removed from components within the intake system improves engine responsiveness, even if the effect is subtle
-
Dimensional stability under heat — carbon fiber doesn't expand and contract with temperature the way some plastics do, maintaining the stack's precise geometry more consistently through repeated heating and cooling cycles

Is This Upgrade Worth Adding?
Speed stacks are a part many riders overlook when thinking about intake development, focusing only on a performance air filter. The filter determines how much air can reach the engine, but the stacks determine how that air moves in the final moment before combustion — making this a logical complementary upgrade for riders who've already upgraded their filter and want to push the intake improvement a step deeper.
A realistic note: the practical performance effect is usually more noticeable when combined with other intake, exhaust, and ECU tuning changes, rather than as an isolated standalone part. If you're building a comprehensive engine modification, this piece is a logical part of the full picture.
Frequently Asked Questions
Does installing speed stacks require ECU remapping?
The airflow change from this part alone is typically less significant than a full filter change, but if you're combining it with other intake or exhaust modifications, remapping your fuel curve ensures you get the full benefit of all the changes together.
Does this part fit models other than the GSXR1000R?
The product currently available in this collection is built specifically for the GSXR1000R (2017-2024). If your bike is a different model, contact us to ask about future availability.

Final Thoughts:
Sometimes the real performance difference comes from the parts nobody sees. CarbonSmith's speed stacks are a precise example of that — a small detail with a genuinely real engineering effect.
