There is NO such thing as that Last Statement you made about "Not Breaking the Bank". But do keep in Mind that the Terms are different meanings: Performance, Horsepower, Sound and Looks are all different. Many people confuse the first two all the time. My Opinion Go with Performance, Sound and Looks. A (CAI) Intake, Exhaust and Tune will give you Performance that you will be Happy with. Exhaust is by your choice and Taste. Intake also, some Intakes require Tunes, some do not require Tunes. Tunes can be Store Bought or Custom made.
