[tor*p*do]

Putting a C4 chamber in my SN.
Planning on dual cooling to dual tapped exhaust mani.
Out the back of the head, into bottom of pipe.
Out of the top of the pipe to pisser with a T to FCV and stinger
Front of head to pisser (4 mm restricted)
Also, how are you setting headpipe screws?
I was planning to start with topo closed, mid 1/2 turn open and bottom 1 turn open.

Any advice?
