    Used fuel system cleaner now cats sound clogged?

    As stated in title. Used a fuel system cleaner as I usually do every other oil change. Went through the entire tank of gas within 4-5 days. Started the car the following morning and I now have a pretty sluggish sounding exhaust. Sounds like it has an exhaust leak now but only makes the sounds at idle and under acceleration, not when letting off the throttle. Seems like the sound is coming from the middle area of the car. Power has dropped just a little but its mostly the sound. Clogged cat? What do you guys think? Had a recent tune up probably 7500 miles ago with new injectors, plugs etc. Stock M20 here. Any help would be great!
