Thinking of changing my backbox from Firestorm to something quieter (due to iminent arrival of small person) is it as simple as unbolting said firestorm and bolting on new backbox. I have a TSL decat system at the moment.

May sound a stupid question but I am a bit of a numptie.

The back box can be removed easily. Remove the two nuts & bolts from the back box where it joins the centre section pipe. Pull away the two rubber mounts from the rear box hangers & it should come off easily then. Re-fitting just the same in the opposite order, oh and use a new gasket from the centre section to back box.

Sometimes the centre sections are different too......
