check it out.

cut it open.

gut it, preserving header legnth. Make silencer out of steel pipe and 1" ss perforated tubing.Modify exit pipe to accept 1" silencer tube

pack it and put it together.

pop rivet it closed using high temp copper sealant(fingers crossed), and paint the rivets to disguise the alteration.Note, the cover required a second donor exhaust so I could cut the cover larger than the opening in the first pipe.

forgot this shot.
