i ended up cutting the box off with an angle grinder fibreglassing
the pipe.. then sikaflexing under the fibreglass.. and then coated
the whole lot in black sika just to ease paranoia.. then cut the nipple
for the hose.. did the same.. and left it all over night.. and she runs sweet
makes an awesome induction rumble haha
also did a fair service as in plugs, oil, filters flushed it all.. runs beautifullyy
and heres a pic of what i did lol
