Hi, my son has just bought a 2nd hand irmscher double d backbox, I,m currently struggling to get original box off but it doesn't look as though this exhaust will fit onto the middle section being a larger diameter, will I need a pipe reducer & if so what size. Corsa 1.2 sxiplus 2006reg.
Any advice appreciated thanks...

Hi. I dont know on sizes. Are you not able to check using calipers to find the inner and outer pipe diameters you need to buy something ? You may even be lucky enough to find the outer diameter of the old pipe matches the inner diameter of the replacement box in which case you could cut a short length of old pipe and use it as an adapter.
