Frequently Asked Questions
Does this require any welding or modification to install?
No welding needed — this is a bolt-on header. You'll connect it to the turbo inlet and exhaust system using factory mounting points. Verify all bolt holes align before final assembly.
Will I need a new gasket and hardware to complete the install?
The header itself comes bare. Source a quality exhaust gasket rated for bi-turbo applications and stainless steel bolts appropriate for your system — these are not included and vary by your existing exhaust configuration.
Can I paint or coat this after installation?
Stainless steel doesn't require coating for durability, but if you want a finished look, heat-resistant ceramic or high-temp coating can be applied post-install. Let any finish cure fully before first heat cycle.
