I have made up my mind on getting magnaflows after winter. My question is should i get the 4"x9" ovals or try the 4" round. I am going to have a true dual set-up. I want to know if the 4" round mufflers will be too loud and have interior resonance. I have dual super 40's right now, and i'm not real happy with them. They have too much drone and interior noise. Let me know what u guys think. thanks

 

i know the ovals will be quiet with little resonance , the round unless there magnapacks should be about the same
