I am trying to decide if my Project Ultimate 3G is going to have a flowmaster 50 or 60 series muffler. I have a few questions though, how much louder than stock are both of these mufflers and which one will give me the biggest performance boost?
I ask this because I prefer quieter cars and I really like the stock 3G sound. I want a performance muffle, but not one that is going to cause me to go deaf or get into trouble with the law.
Any help is appreciated.
