slp header gasket question

[Dirtbikekid1998]

Hello I am going to be replacing the gasket that came with the slp header with a Yamaha gasket(the gasket between the head and the header). Do I need to use a sealant with the new Yamaha header gasket like a copper silicone? Or is just the new gasket ok?

My slp header didn't come with one, i reused the original gasket with no issues yet, mine also wasn't polished up like some but i only paid $420 for it shipped on amazon.

I also have used stock gasket for 3 or 4 headers. No sealant just torque bolts.

Do not use the gasket that comes with the header- it will fail. After the ulmer header gasket failed I put a oem gasket on and have had no issues.
