FAQs
Should I skip Stage 1 and buy Stage 2?
Stage 2 makes sense if you already want the Stage 1 base plus the rear exhaust path.
Does Stage 2 require professional install?
Many experienced owners can handle the hardware, but tune and setup decisions should be checked by a qualified installer.
Is Stage 2 the right setup for casual riding?
Stage 2 is best when you want a stronger package than the first bolt-on step while keeping the build manageable.
How fast does the kit ship?
In-stock GT40 parts normally ship from the current GT40 fulfillment queue. Check the product page before checkout for live availability.
Will this affect my factory warranty?
Any performance modification can affect factory warranty coverage. Confirm with your dealer and installer before modifying a new craft.
Can GT40 help confirm my exact model?
Yes. Use your exact year, model, and engine when ordering so the GT40 team can confirm the correct fitment path.
