[smell my dirty poodle]

I installed a weber carb on my i6 few monthes back. wow what an improvement. Last week I instaled a borla header and cat-back and again what an improvement! To top it off the sound of that borla is awsome
Intake and exhaust man, is the best and most eccinomical way to start. You dont have to go with the big name stuff nessissarily but ask around.The borla set up is expensive but quality. And fits real nice.
