I assume it would overboost mate,

I would get a tune to be on the safe side, and upgrade the cat while your at it !

Why would you bother with the dump pipe if you don't want to retune? Are you doing some mods in stages and want to drive with it like that for a while? Most of the boost spikes are caused by free flowing cats and not the dump pipe.

Your going to pay someone to install it $, your going to run the risk of damaging something (maybe) $$. You will gain very little from this waste of $$$. Keep the pipe on the shelf until you get a cat and a tune. Do it all at once.

Nah its not that, I'm putting the stock exhaust back on, but I'm having trouble finding a stock dump pipe.

edit: And I'm not going to pay someone to install it, it's not that hard of a job.

I dont think it would be a problem. at the end of the day the stock cat is still going to restrict the exhaust gasses the same regardless of the dump size. check boost and a/f just in case.

Thanks mate, as it turns out one has just turned up so no need to run the 4" anymore.

Just another quick question, the wastegate has been ported on the turbo, and the fuel pump is a walbro item. Will these affect the stock tune?

No. Had fuel pump installed and my wastegate ported with flapper mod at 25k. Been driving it around for 50K on a stock tune and had no problems what so ever

why did you waste your money on said mods if you were just going to leave the stock tune in place?!
