Downpipe size on 850 T5R

[chrjen]

As the title says, what is the size of the standard downpipe on my T5R. The reason Im asking is whether I need a 2½ or 3" race-cat to weld on instead of the existing cat.

2.5" I think.

Its just under 2.5inch in diameter. I will check when I get home from work as I have two cats in the boot of my car.

Its 2 and 3/8" or 60mm (just over).
