I am thinking about getting duals on my 2000 G20t. What they said they would do was cut out the muffler and split the existing pipes, then add two balls (supposed to work like mufflers but are very small) and run the piping around the gas tank and back to the original place. They say it will look factory (as I will get that exhaust cutout on the other side) but I'm worried about how it will sound. Has anyone done this? pics? Does anyone know if this is a safe thing to do? Will it negatively effect the reliability of the car? Any opinions are appreciated - having problems deciding if i want to spend big bucks when there is the possibility my car will sound like sh*^!
