Do these require welding or cutting to install?

No. These bolt directly to factory mounting points with no modifications to your engine bay or exhaust system.

Will I need a new exhaust system to use these headers?

Your existing exhaust will bolt up, but pairing headers with a cat-back system optimizes flow. Check your current exhaust diameter and collector size before ordering.

Do these come with gaskets and hardware?

Confirm gasket and fastener inclusion before checkout. Have OEM gaskets and bolts on hand as backup — sourcing them separately after purchase takes time.
