My 90' does the same thing. I've changed the thermostat twice, the sending unit twice, checked the wiring, and even changed the gauge.
It still "heats up" to about 130, and there she sits. The only time it's gone higher is once when I left the cap off by mistake after changing the coolant, and it overheated when it all leaked out.

Mine topped out at 210 while idling then dropped a tad. Of course when I pulled the sending unit plug the retaining tab broke. Such is life.

You'll gain horsepower, torque and throttle response. Be sure to have your muffler guy tuck the pipe up close to the motor when he builds it.

Bottom line, I don't think anybody is gonna notice a difference with the downpipe crush there or removed. Removing it may make it more difficult to pass emissions in any particular place, but it isn't considered emissions equipment.
