RE: MAC Pipe TT Pro46 OMP Edge. Pipe help Please!
Don,
I am installing a TT .46 on a OMP Edge540FF as well, with a mousse can muffler on a Mac's header.
I used the whole header. Just cut off about an 1-1/2" and JB Weld it into the bottom of the mousse can. Put a 1/4" alum stinger about 3" long into the top of the can. Haven't ran mine yet, but this is what the other guys have at our field.
