Frequently Asked Questions
Do I need new gaskets or hardware to install this?
You'll want fresh header gaskets — reusing old ones risks leaks. Check your engine bay for existing fastener condition; most installs reuse factory bolts, but picking up a new gasket set before you start is the smart move.
Can I run this header without a tune or custom exhaust?
Yes. This header bolts in and works with your stock exhaust system. You'll see airflow improvement right away, but pairing it with a catback exhaust and ECU tune will maximize the gains.
Will I need to remove anything else to access the manifold bolts?
Depends on your engine bay layout — some tight spots may require moving hoses or brackets temporarily. Do a test-fit and have a camera or phone handy to see your work angle. No permanent modifications needed.
