Sound like its getting hot. How does it run? Does the exhaust smell like bad eggs? Might need a cat but those usually only go bad due to other issues.

it runs good--no rotten egg smell-an no check engine light on

There can still be pending codes. try to get it scanned. other than that you may need to just crawl under it and see if you can see whats popping.
