What is the stock exhaust size for Turbos and Non-Turbos?

 

[mysupra87]

21/2 i BELIEVE to be for both.

 

[1988SupraDreams]

Hmm.. Anyone else?

 

[flubyux2]

im going to say, from the turbo elbow to the cat, its 60mm, or 2.25". after the cat, it may go up to the 2.5".

Wrong, both cat backs are IDENTICAL, same part numbers from toyota.

^ Not true! Toyota P/N 17430-42062 for GTE from 8/88 to 5/93 & 17430- 42052 for GE with same application dates as the GTE.
A different P/N mean it's a different part.

what about 86.5-8/88? is it the same or?

 

[BadBoyToy]

I measured my Turbo exhaust and it is 2.5". I don't have a NA exhaust to measure now but when I was buying a cat for my NA I measured it at 2.25. Both were '88s.

 

[pimptrizkit]
