    I did my 260 water box, I assume they would be the same internally, I took a dremel (would be faster and better with an air powered cutting wheel) and cut all around the inlet end right next to the weld a few mm into the waterbox then did a V into the front cap to get around the inlet tube, once it was open I punched 3 holes thru the baffle with a hole saw and finished the rest up with a reciprocating saw cutting the exit tube flush with the exterior of the box. There's what looks to be a double floor in the bottom of the box but you just leave that alone, then had it welded back up. It sounds deeper than my old tdr box which is probably because it is bigger
