if you scroll down in this following thread to my second post you'll find the answer. I'd post it here, but it's not a one word answer you'll see.

ok, maybe I should have just posted the info here before, but this is the info from that other thread for the link-aphobic:

OK:

I just measured the piping with digital calipers.

I took many measurements and here are the definitive results:

From the resonator back to the muffler canister:
Most of the measurements were approximately 2.36. As high as 2.38 at one point and as low as 2.21 on one bend.
There is a short section of piping after the flange but before the muffler canister and thats 2.36

From the muffler canister to the tip:
Suprising Results:
2.11 all over.

(From when I was under my car putting in my new clutch, I measured the piping around the 2nd O2 sensor behind the CAT and that was about 2.36.)

------------------------------------------------------------------------------

So it does not surprise me that the piping of many aftermarket exhausts for the Celica is advertised at 60 mm (or about 2.36).
