I just bought a 2012 Audi A6 3.0T Prestige and love the car. I do however want to try and get some more horsepower and torque but doing it without breaking the bank. Looking for affordable options to do that. I know there are some tunes out there but not sure what to look for or get that will work and be affordable. Also, looking to make this sound a little better then where it sits. I don't want to replace the whole exhaust system, so maybe there are some alternatives to make sound beefier. Open to ideas. Thanks and let me know.
