I don't think I would risk trying this on the car. The exhaust is a one person job, pretty simple to remove, and once you've done it, it's about 8 minutes to remove both sides. (not that you need to remove both sides). And if you are going to try and 'lean' on it after heating, you will want it solidly restrained, not subject to the flex of the rubber mountings under the mufflers.
