Rang my dealer today to order some bits for an astra I was doing. Parts lad says to me, "Oh you know that Irmscher exhaust 'Y' piece we got you...well they're on back order now at Irmscher, I was talking to the bloke at Irmy yesterday and he says there has been a sudden rush on people getting them for the 1.9cdti, apparently someone has done it and put up on a vectra forum how to do it and the part numbers of the bits needed, so we've ran out...."

So there we are guys, I have brought Irmscher to their knees (well in the 'Y' piece depatment anyway).

Apologies to anybody who now finds themself waiting for one lol
