With turbo, you can't really go too big... the more free flowing you make it, the more power you will gain, but also noise will increase with size.

Just suss out local exhaust shops and ask any mates if they have done the same thing.. exhaust is all trial and error.. I'd suggest 2.5".... 2" is a bit small and 3" may be a touch big and noisy, depending on what mufflers/resonators you plan to run.. if any :lol:
I always recommend to run a quality muffler like Lukey etc. to obtain a nice sounding note out of it and have none of that rattly/tinny noise.

For yours I would say 2.5" would be ideal.

If there was a way to increase your power by roughly 25%, then a 3" would work...but noise does become a factor.

I have a 3" on my 2.5l Fender TD5. But it has been chipped to give heaps more kw.

And it is L-O-U-D :armsup:

as the fellers said 2.5" will be just about perfect for ya...

I believe the early discovery's with a 2.4 TDI come with a 2.5" pipe on em..
