what exhaust tips can fit on my 2005 s4 that will add better sound?

 

exhaust tips arent gonna do you anygood in the sound department, unless you go with something you see on a big jacked up truck and if you do that, I will come and kick your but, No but seriosly, the best way to get sound out of your car is to buy a new muffler, there are a few companies that make very nice pieces for your car that will also alowe it to breath alittle easyr= more hp.

 

what do you suggest?
