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.

Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
