getting new couplers

[alexV]

Im getting new couplers for my WR hardpipes, and i'm tring to figure out the diameters i will need. i want to verify some info. The IC inlet size is 2.00 for both hot and cold pipes, right? Same for the turbo inlet size where it connects to the hot pipe? the throttle body inlet is also 2.00, right?

Throttle body - 2.5"
Turbo outlet (to hotpipe) - 2.0"
Turbo inlet (from intake) - 2.25"

Not sure about the SMIC since I don't have one of those laying around.

ok. so it looks like for the wr pipes i will need
3 x 2.500 couplers
3 x 2.5 to 2.0 reducers
