Does anyone know whether a CS400 downpipe can be adapted to fit a twinscroll hatchback and if so what sort of figure would the work cost?
Thanks.

Youd need the different flange welded on plus the angle of downpipe needs adjusted as it wont work with standard fit turbo due to cs400 turbo having a very slight twist so that it could clear the throttle body.

Cant remember who done it on here previous but that was std single scroll turbo but I saved the pics of the adjustment needed

Thanks Gambit that's very useful info! So from what you describe and looking at the photos, it is it "as simple as" cutting the piece of pipe before the first cat in a slanted way, making a new flange and possibly modifying (extending/shortening?) the other end of it which fits the centre section if needed?
Does anyone know what cats the system has? There are 2 by the looks of it.

Don’t worry Fivos, I have a twin scroll down pipe for sale if you mess it up

I am not planning to chop the OEM Hugh but good to know!

are the OEM twinscroll downpipes a different length to OEM single scroll downpipes? The CS400 downpipe is same length as single scroll OEM downpipe (then has flex joiner pipe, centre pipe & rear box - 4 part system)

ideally you need an OEM twinscroll downpipe to hand to use as a reference when tweaking the CS400 downpipe. Yours will require a bit more work with the turbo flange needing changed - just need to find yourself a decent fabricator
