Hey guys, I am new to this forum and a fairly new Audi owner. I love purchased my 2002 A4 3.0 used with 17000 miles and am looking to make some modifications. I heard a chip is a great place to start, but i would like to know what the best chips are and what exactly they do. I heard you lose gas mileage bun not sure if this was a rumor. I would like to add maybe 20 to 30 hp, but do not know much about cars. A new exhaust system is kind of expensive but maybe some mufflers can help performance as well. I also was hoping maybe some people had some suggestions on whether sway bars were a good purchase as well (at least worth the money). Finally if anyone knows a good place to get a chrome grill or custom painted grill that would be really helpfull. I have a dolphin grey color and thought maybe a matching grey grill would look cool. Sorry for all the questions just do not know were to start. Thanks for reading.
