I have a very silly Q but made me wondering, If both mid pipes of the 1M and the N55 are identical except for the 2nd Cat, wasn’t it just easier to cut off the cat from the original mid pipe of the 1m and just do some good welding job with a piece of straight pipe ?
Easier, no. Putting the N55 midpipes on is a simple unbolt old, bolt-on new job. Adding cutting and welding in the middle can't reallyy be easier can it, unless you were crazily cosidering somehow to to the cutting and welding in-place? ;-)
