Weird Exhaust Sound Options

[MonsterBOX]

over the course of the year my car has developed a weird exhaust sound...this only occurs in lower rpm range when i apply heavy accelerator or rev the engine...it kind of makes a low flutter sound..at first it wasnt noticeable but after driving my car hard for the past month or so its really noticeable it kind of sounds like a harley when they have they fluttery sound during acceleration...its hard to explain...it is the loudest when trying to climb a hill in a higher gear such at 4th such as 3rd...to a gear too high but just when u need extra gas in the lower rpm range...maybe it is a leak in the exhaust many gasket? any ideas as to what this is would be greatly appreciated...its not knocking by the way either and im using 93 octane

aight i tried some stuff out and its really weird results....when i first start up the car before its warmed up all the way and i drive off after bout 30 seconds of running the sound isnt there for about 10 minutes or so and the engine seems to pull really hard compared to usual but after bout 10 minutes when the temp gauge is centered it starts making the weird sound up hills and any time i apply gas and the performance dramatically declines and stays like this throughout the whole course of the driving until the car has been shut off and driven after it is cooled down
