Getting a problem more and more: the oem pipe is made from corrosive steel material. Had some time at work and prepared a new one from stainless steel...will last for eternity. The pipe wall thickness is same as original: 1 mm and the T-fittings 1.5 mm. So in total the weight of the stainless steel variation is only nearly 100 gramm higher than the oem pipe.
