One of the best tools I ever bought was an exhaust smoke machine. I've used it on all of my cars to check for exhaust leaks. With the engine off, it forces smoke into the tailpipe and shows the leaks. It makes the driving experience better by not smelling like exhaust when I get home. The one I have is "Autoline Pro", costing a little over $100. https://www.amazon.com/AutoLine-Pro-Automotive-Detector-Diagnostic/dp/B07JVT1NG2 I then disassemble any leaking joints and use an exhaust assembly paste, i.e. Hylomar EAP5.
