piggies are stock downpipes with gutted cats. It will sound meaner and youll get a few HP. Piggies are just a cheap way to upgrade your downpipes.

 

well said addict, I love it,true stage 2

 

Like everyone else before me said go with borla, it is a widely known company and has an amazing sound, I have even seen Ferrari's with the borla on in showrooms

 

well i have the AWE twin1 right now and i love the sound. it has a mean note to it. I was going to get the UUC exhaust, but they discontinued it when i was ready to purchase. The AWE and UUC are supposely the loudest exhuasts for the audi s4.. To add on to me twin1 im getting some piggie pipes really soon. I love my AWE, sounds great and looks amazing
