I am doing an overhaul on my 08. I am putting a new head pipe on in the process. It's a FMF stainless steel. I have a Lexx exhaust and mid pipe. IS there a certain type of sealant I should use where the mid pipe meets the head pipe? I was just going to use a high temp gasket maker but I'm not sure if that will work or if I should use anything at all. Thanks for the help!
