Year, brand, model family, trim/engine, and category drive the result. Intake and catch-can rules use GT40Marine internal confirmation. Hull-sensitive parts stay gated by platform, routing, and exact machine data.
Why this works
Choose the machine first, then compare stages that belong on that platform.
Each kit path organizes the core parts, support parts, and optional upgrades together.
Start simple, step up later, and avoid buying random parts that fight the build.
Designed around airflow, cooling, tune needs, install difficulty, and fitment confidence.
Stage language
The point is not to make every rider buy the biggest package. The point is to make the right next step obvious.
Best first upgrade. Simple bolt-on and tune-focused paths for riders who want sharper response without overbuilding.
More airflow, cooling, acceleration, and supporting parts for a stronger, more complete package.
Serious performance builds with higher-output parts and a stronger setup plan.
A higher-end Stage 3 path with additional support parts to reduce weak links.
Advanced race-level builds where fuel, tuning, installation quality, and supporting systems all matter.
