V70 2.5T (2005) looking for 300HP, what upgrades?

[redblockturbo]

I've got a V70 2.5T (2005) SE.

I recently had a stage one remap which has improved the car dramatically.

I'm looking for the next stage of tuning to build a up to 300HP car as I believe that's the max the 2.5T can handle without putting cylinder sleeves and new piston and rods.

I currently need a new exhaust as the back box has fallen off and thought it was a good excuse to upgrade!

What I'd like to know is what are the obvious upgrades. The car is completely stock apart from the map.

Some people have said that a bigger turbo and injectors plus a new map is the way to go.

Others have said, a 3" down-pipe and catless 3" exhaust is the way to go.

All thoughts welcome.
