done that...I already tried poking around. Can't seem to find anything. Like I already said, I'm leaning toward exhaust system because it's worse when the car is under load. It's probably a leak, so I think I'm gonna take it to a muffler shop Friday and see if they can find any leaks. I honestly think it's a Cat, though. Or maybe I'm just hoping it's a cat so I can get a new one and "regain some lost power"
