I am thinking of getting some Innovative F/A devices. Would I be able to weld in bungs into my Stainless Marine tails? Where? They are long TRS tails that are dry to the tip.

Gotta be close enuf to the end & have enuf room to get the Tig all the way around or cut a donut out and weld the bung inside and tig the donut back shut on the bottom a lil less noticable

you can send them back to stainless marine, they will install a stainless steel bung for about $75 each (last I did it)

Had the EMI's long pipes done like this.
