Frequently Asked Questions
Will I need gaskets or hardware to install this?
You'll need header gaskets for the flange bolts — those don't ship with the header. Use factory-spec fasteners to secure at the mounting points.
Can I bolt this to my stock exhaust system?
Yes. The collector outlet matches stock sizing, so it connects to your existing downpipe or exhaust without adapters.
Does this need any coating or can I run it bare?
Bare stainless will develop a light patina over time but won't rust. If you want a polished or coated finish, apply it before installation — easier to handle the header loose.
