Ok #1 I have a RB true dual, I am about to put it all on and wondered if I can touch the exhaust during install or should I wear some kinda protection to keep body oils off from it?

2nd question, the things that screw into the transmission with the wires coming off of them, are these the kinda things that if not tight will cause oil leaks?

 

1) No worries, just wipe down the parts that show before you get it hot.
I love the stereo sound of a full dual NA.
And the growl it makes at mid band is sweet.

2) Yes they can leak some. I use RTV sealant on nearly all seals. Use a thin coat, let it set a few minutes, assemble.
