Frequently Asked Questions
Do I need to use any gasket sealant or replace the gaskets during installation?
Use a fresh exhaust gasket at the manifold flange — reusing the old one risks leaks. Apply a light coat of high-temp gasket sealant to both sides. Don't over-apply; it can squeeze out into the ports.
Will this header fit my current exhaust system, or do I need to modify the downpipe connection?
The collector outlet diameter is standard — most bolt-to-flange downpipes will fit without modification. Test-fit before final tightening to confirm alignment with your existing piping.
Should I wrap the header tubes to manage underhood heat?
Not required, but stainless headers run hot. Wrapping reduces radiant heat damage to nearby wiring and hoses. Use exhaust wrap rated for sustained 1200°F+ temperatures and install dry; wet wraps trap moisture and speed corrosion.
