Anyone know the length of the test pipe

[Sweet6]

for the THDP? In inches? The car I have with a THDP has a cat on it and I want to take it off. Please post if you know.

TIA

I just saw this was for a TTA, but on a GN using a 3" THDP I believe the test pipe/ or cut-out is 13 1/2".

Just to make sure, that is with the THDP correct?
