Frequently Asked Questions

Do these headers need gaskets when I install them?

You'll want fresh header gaskets at the cylinder head ports. Reusing old gaskets can cause exhaust leaks. Gaskets aren't included — grab a set rated for your engine before installation.

Will I need to remove anything under the car to fit these?

Shorty headers are compact, but test-fit clearance with your existing exhaust piping before final tightening. Depending on what's downstream, you might need to adjust or reposition your mid-pipe or catalytic converter.

Can I return these if they don't fit?

Contact our support team with photos of your setup. Returns are handled on a case-by-case basis — make sure you're confirming fitment with your exact engine code before ordering.
