They'll probably hurt your ears more than the motor! The only time I would think the exhaust system will affect a gas engine is at wide open throttle operation. Then you'll get a little more air through the engine (and more power) and depending on your carburetor performance, you might lean out the mixture and that could cause some excessive temperature on the exhaust valves. But very few of us run at wide open throttle and if so not for very long. On a diesel, I think it would cause you to run with a smaller fuel/air ratio at all rpms and that means you'd loose some power.
