Anyone know what size the exhaust pipe is at the muffler on an 85 Turbo Coupe?

the pipe from the cat to the muffler,
and the 'tailpipe' (from muffler over-axle to chrome tip) are both 2" O.D.

(which means the I.D. of the 'over-axle' crimp-bend is about 1.5')

my 86 XR7 picked up a bunch of power when I went 2.5" (crimp-bent) from the turbo down-pipe all the way back ..
