Frequently Asked Questions
Will this bolt directly to the factory exhaust manifold location?
This header is designed to replace the factory cast manifold at the cylinder head. Verify bolt hole alignment and O2 sensor bung location before final installation—test-fit the assembly on the engine first.
Do I need to prep or coat the stainless steel before installation?
Stainless steel doesn't require primer or paint. Install it as-is. High-temperature exhaust gases will naturally patina the outer surface over time.
What's the warranty on this header?
Return or warranty details aren't specified in the product data—reach out to ModSupply directly with your order number for coverage information.
