Hey guys im wanting to upgrade the exhaust on my s4, its all stock atm. i fell in love soon as i heard the sound coming from this thing http://www.youtube.com/profile?user=...M#grid/uploads, and after watching videos of jens eklunds urs4. i know im not going to get exactly the same note with my car since they have extensive mods but i basically want to know how to get the burliest, raspiest note i can get from the exhaust. what size dp, 3", 3.5"? race cat or no cat, single muffler? i only drive the car on weekends mostly so im not too fussed about it being too noisy etc.
any help would be appreciated.
cheers.
