Will these bolt directly to my engine or do I need custom exhaust work?

Headers are the bolt-on component — they mate to the cylinder head. Connecting to your existing exhaust system or running custom piping downstream depends on your setup, but the header itself bolts in place.

Do I need to prep or paint stainless before installation?

Stainless doesn't require priming or painting. Install as-is. You'll see natural oxidation over time, which is normal — stainless won't rust through.

What fasteners or gaskets should I use?

Headers ship as the core assembly. Source your own header gaskets and fasteners based on your engine's bolt pattern and torque specs — refer to your engine manual for proper specifications.
