Frequently Asked Questions
Do I need to install a new downpipe or can I use my factory one?
Your factory downpipe bolts directly to the merge collector — no modification needed. Test-fit to confirm clearance at the flange before final tightening.
Does this header require any prep work before installation?
The header ships ready to install. No painting or coating is required. Clean the factory mounting surface on the engine block and cylinder head to ensure a tight gasket seal.
What gaskets or hardware do I need to complete the job?
You'll need a header gasket set for your engine — the header itself does not include gaskets or mounting bolts. Check your service manual for torque specs and gasket part numbers specific to your vehicle.
