Are TRD duals a true 2.5” from flange to tailpipe?

Hello. Like it says, are the TRD duals a true 2.5”. Or do they nave a smaller diameter?
Thank you.

 

I havent measured a TRD system... but have seen pics online.
The pipe diameter forward of the mufflers appears to be the same as stock.
When I replaced my stock system with a 2.5" system... I (rough) measured the OEM pipes and they were just over 2", maybe 2-1/8" O.D.
Im pretty sure the TRD pipes (front of mufflers) are the same size... with what appears to be 2.5" tailpipes.

Would be nice if someone chimed in that has the TRD system nearby to measure.

 

Thanks Dragracer. Your observations on the pre-muff (hu hu hu) pipes look less than 2.5, from the photos I have seen.
Thank you.
