[Shotimes] exhaust thoughts. Help!

The gen1 wouldn't be so bad with a single (as for looks) as the rear fascia
hangs lower.  Also, the early 92 rear fascia doesn't have the larger exhaust
cut outs that the late 92-95 ones do, so you could probably make it look
better with an early one vs a later one.

The real crap of the SHO isn't so much the 2-1-2 as much as it is the outlet
for the Ypipe (including the aftermarket PP units) is 2.25", same as the
individual pipes off the manifolds.  Depending on your hp/rpm level, you
need at least 2.5" up to 3" outlet there, with same size piping from there.

Lance Cheney's 92 has or had a nice 3" collector and 3" piping all the way
back with a single muffler.  His early 3.2L (ATX longblock) made 250 fwhp,
and IIRC came from about mid 230ish before he ran the 3" system.

I think Dan Brabec's was similar, although his simply dumped in front of the
rear wheel (NASA race car).  IIRC his last dyno pull on a +40 cam 3.2L was
264 whp.
