Conical, flat or angled flange turbine housing? (if this is the engine I sold you I don't actualy remember which one it had on it....
I have multiple downpipes so if we know which one you need.... I has it...
The Downpipe is just mild steel so no reason it can't be welded.... this is possibly the best solution as its same labor to pull it out and weld it as to fit another one
even with a second hand one.... you may want to get it blasted and cleaned just to make sure it does not have a crack or thin spot either
