TRD Cat-Back Exhaust Question

By chance, anyone know the OD of the tubing used in the TRD cat-back exhaust system? Also, anyone know what type of muffler used in it? This is the Bosal made system, not the Borla system.

 

I thought Borla supplied all TRD exhaust for our 2nd gens...

 

Bosal does the exhaust for ours. I'm trying to find out if they use 2-1/4" or 2-1/2" tubing. From what I've seen, the cylinder muffler has two vertical plates inside and evenly spaced from the middle. I'm thinking the inside might be similar to a Gibson Super Flow Round muffler.

 

Interesting. Thanks for the clarification.
Hope someone can chime in with an answer.
