Frequently Asked Questions
Will this header fit my stock exhaust system?
The header connects at factory mounting points. Your existing exhaust components may require adapter fitting or modification depending on your current setup — verify collector outlet size before ordering.
Do I need to prep or paint this before installation?
Stainless steel won't rust, so paint is not required. The header will develop a natural patina under heat. If you prefer a polished look, light polishing before install will keep it brighter longer.
What fasteners do I need to bolt this on?
Hardware to mount the header at the engine block is not included — source bolts that match your factory mounting points. Your vehicle service manual will specify the correct size and torque spec.
