Frequently Asked Questions
Do I need new gaskets or a new downpipe to use this header?
Factory gaskets may reseal if you're careful during removal, but new header gaskets are strongly recommended. Your current downpipe will bolt directly to the collector — no modifications needed there.
Should I paint this before or after installation?
Stainless steel doesn't rust, so paint is optional. Many builders leave it bare and let exhaust heat create a natural patina. If you want color, use high-temp engine paint rated for 1200°F+ and apply before bolting it on.
Will this fit with my stock air intake and oxygen sensors?
Header design matches factory locations. You may need to verify oxygen sensor boss alignment with your current intake setup — test-fit before final tightening. Some custom intakes require minor clearance work.
