I have a 2007 A4 2.0t that is stock. I am looking for more power and i would like to do the APR ECU. What other parts are a must to keep my car running like a champ. Also i am looking for suggestions as to which exhaust/test pipe to get. I want a deep throaty sound. Id like it pretty loud but not obnoxious. Thanks for the help.

 

all you NEED is a High Pressure Fuel Pump, but it is recommend to also install Testpipe, Intake & Catback Exhaust

if you just do the test pipe and intake you will notice a nice exhaust note w/o being annoying

 

Thanks ill surely be adding those things. I'm looking to jump straight to stage 2+ so else would I be needing? Also I'd like to do exhaust who makes the top 2 or 3 best sounds for ill probably buy the eurocode test pipe so which exhaust will sound mean with that? keep in mind its an automatic with awd.
