Here we go my Rx8 was flooded so i Deflooded it myself. car is working fine idle is stable. the only difference is when i rev the car past 5k i hear a POP noise comming from the exaust. what could be causing this? Broken or blocked Cat?

 

Do the normal checks. Plugs coils wires. Run the car for about 20-25 min then check the temp of ur cat. Usually a blocked cat will GLOW. But that doesn't exactly mean it will. All of our cars "pop". Some more than others but usually it's nothing to cause concern.
