I used the Hi temp sealant on the joint between the header pipe and the right muffler. Luckily, only had to use the exhaust cement on the bung hole where the oxygen sensor used to be. Don't plan on ever opening that back up. Have been laying off the Rocket since I did the triples and Jardines which took a lot of will power but have my dyno on Saturday and then will finally open her up to experience the difference!
Will post results when I get them.
