Do these headers work with the factory catalytic converter?

Yes—these long tubes are designed to bolt directly to your factory converter. The header flange matches OEM mounting points, so no adapters or modifications are needed on the cat side.

Will I need gaskets or sealant when installing these?

You'll want high-temperature gaskets where the header bolts to the cylinder head. The header-to-cat connection typically uses the factory gasket or a new OEM-style gasket. Check your service manual for the correct spec before install.

What about heat shielding or wrapping?

These headers will get hot during operation. Depending on your engine bay layout, you may want heat wrap or aftermarket shielding to protect nearby components. Test-fit first to see what clearance you have, then decide if protection is needed.
