Toyota Hi ace exahasted exhaust

Ok the system i want is very expensive, is there any reason why i can not use old systems welded and clamped together as its only my rear pip thtas holes, i have a supply of endless scrap systems, would this be ok for mot if its non leaking. Tim.

Welder then, mig, oxy torch or arc, what u say, was going to get one anyway.

The message from "

" contains these words:

If the gasses largely [1] stay in from one end to the other that's fine. I've welded up loads of exhausts - some of which have been still passing MOTs three or four years later.

[1] I say largely 'cos some tiny leaks are allowable. Indeed, some systems have tiddly drainholes in the bottoms of the boxes.

£100 for a new one at the above I assume it's a 2.4D
