Will this bolt directly to my stock exhaust system?

The header bolts to factory mounting points on the engine. Your existing downpipe or cat-back system will need to be checked for fitment at the header outlet — some buyers adapt the connection point depending on their exhaust setup.

Do I need to prep or paint this before installation?

Stainless steel doesn't require primer or paint. Out of the box, it's ready to bolt on. The natural finish will develop a patina under heat, which is normal and does not affect function.

What gaskets or hardware come with this?

Header assembly only — gaskets and fasteners are not included. Use OEM gaskets at the header flange and confirm your existing bolts are in good condition before install.
