You should still follow the cold weather starting drill after running the block heater as it takes a lot of load off the battery and starter too.....

DON'T try to tighten any exhaust parts ! . they'll break off making things worse .

I've had mixed results with exhaust pipe wraps, no reason not to try though .

If you have to drive it with exhaust leaks, open the right rear window 1/4" and run the HVAC fan on high to blow the exhaust out as best it can .

Consider borrowing/ buying a snowmobile suit so you don't freeze your tukis .

This all reminds me of old cars & trucks from the 1940's that never had heaters, accumulated plenty of rust holes and were our daily driver's in the 1960's......
