Frequently Asked Questions
Do I need to replace the exhaust gaskets when I install this?
Yes. Old gaskets compress and won't seal properly against the new header. Grab fresh manifold gaskets before you bolt it on — reusing old ones leads to leaks.
Will this header work with my current exhaust system?
The header bolts to the factory manifold points. What comes after — your downpipe, catalytic converter, muffler — stays the same. No modifications needed downstream unless you're planning a full exhaust overhaul.
Do I need a heat wrap or ceramic coating before installation?
Not required to run it. Stainless naturally handles exhaust heat. Heat wrap is optional if you want to reduce underhood temps or protect nearby hoses and wiring from radiant heat.
