Wanted 2.5" downpipe


I'm looking for a 2.5" downpipe, either in the form of a decat or with a sports cat. Doesn't really matter as I'd put a sports cat into a decat

Does anyone have one they are looking to part with or does anyone know where I can get one that isn't stupidity expensive?

Or am I mad thinking I get all the right piping and get my buddy to weld one together for me?

I made my own, the standard flange to manifold is 2.5" so can be used. then a 90* bend, 35* bend, flexi, cat and 2x lambda bosses.
top pic is 2.5" bottom one is 3" to the cat then 2.5"
