Cat Converter and heat
My GPR is all set for now so I am working on my wifes XLT1200.
D-Plate and Chip is on the way but in the mean time it does have a cat converter installed. Is the operating temp higher when a cat is installed ? I ask because it is noticeably warmer after a ride than my GPR. I verified there were no blockages in the strainer (pump side) or hoses. It is an all stock set up (for now).

A friend of mine let me borrow her 05 GPR last year when my ski was down. I rode it for a couple of hours, and afterwards took it to the spray wash on my way home. I pulled the seat (45min after shutting it off) and it was really, really hot under there.
She still had the catalytic converter in there.
I couldnt believe how hot the pipe was that long after I shut it off.

Thanks WFO - that wakes me feel way better about the heat.

Yup, that Catalytic convertor has a highly exothermic reaction (releases heat) reaction takings place in there. This goes for your car too.
Thats good you have a D-plate on the way. Its preventative maintenance also. the Cat-Con does so much expanding and contracting, they have been known to break apart in the rear portion of the stinger.

nope, thats it.
* torque everything back to proper specs as per the manual upon reinstallation.
* I would also clean that surfaces that the inner grey exhaust coupler meet, the rear bottom rubber stinger boot and the rubber coupler boot where the U-pipe and stinger meet with alcohol or acetone to remvoe and oil/grime so the rubber boots fit well and snug upon reassembly.
* while the rear pipe is out, check your oil lines where they goto your carbs. Inspect them well and make sure there are no signs of leaky fule lines or oil lines especially.
