Default 2.5 to 3" backbox

So I have a 2.5 Middle section and a 3" miltek backbox is the easiest way to get them to join is to get it welded together ?
Thanks

Basically with v band is like two flanges clamped by a band, you will need to weld the flanges to the corresponding pipes. However, if your weldin is not great it be a lot easier to weld them on as you can overlap weld them onto the reducer and then make sure that everything is air tight so you dont get exhaust blowing once all installed.

If you just weld the reducer straight on it be prone to corroding and snapping

i hope that all makes sense or you can take it to a professional garage other than kwick fit to weld the bits together
