Do I need to source gaskets or fasteners separately?

Yes. Header gaskets and bolts are not included. Pick up a quality header gasket set and stainless fasteners rated for exhaust temps — standard hardware from any parts store will work.

Will this work with my stock exhaust or cat-back system?

This header uses factory outlet sizing, so it'll bolt to your existing downpipe or cat-back with no modification. Check your current piping diameter before ordering to confirm clearance at the engine bay.

What prep or coating do I need before installation?

Stainless steel won't rust, so no coating required. Inspect the header face for any debris or damage before bolting on. Use a thin bead of high-temp gasket sealer on both sides of your header gasket for a clean seal.
