I recently purchased a used Mugen header. Should I source a Mugen header gasket from King Motorsports or should I just pick one up from my local Honda dealership. Would you think the gaskets differ in any way?

 

just get a new exhaust manifold gasket from the dealer. The Mugen flange doesn't stray too far from the OEM flange and the oem gasket will do the job in creating a tight seal between the head and the manifold

PS. look into getting a new donut gasket while your at it. Its cheap enough so get it at the same time.

 

Sweet, thanks for the information. I'll make sure to pick up the donut as well.

 

Just reuse the existing gasket. I've reused mine 5-6 times.

 

I agree. Ive reused mine more times than I can count.
