Alright bro i'm not going to list my own exhaust like everyone else is doing seems how i build my own exhaust, but i will answer your question as you asked.
Anything you install must have a muffler with a large body and not just straight through unless you need that raspy sound some people are gunning for, but if it is straight through a resonator or pre-muffler is a must, you are definatly going to want to avoid over sized tips, in case you weren't aware this isn't japan. Unless of course if you want all the unnecessary police attn., remembering this is the commonwealth of vagina.
You also dont want to go over kill with the size of the pipe you purchase. If your turbo you want as close to straight flow as possible. But on the other hand "all motor" cars as the people that are claiming it, you need to have back pressure to sustain mid-range and or low-end torque.
Other then what i listed working at a muffler shop for alsmost two years wll lead you to one conclusion, not every body hates the angry bumble bee's riding around town.

 

Not magnaflow.

 

or any ebay "n1 style" exhaust for that matter

 

Fujitsubo RM01a Exhaust. 2.5" stainless steel and weighs next to nothing. Not too big, may be bit a priced higher than your average exhaust but definitely worth it.

 

DEF BETTER x2.but not made anymore???? thats what i heard anyway

 

greddy evo is also nice,but pricey

 

my Fujitsubo cost me around $800 bucks, but that was years ago,what are exhausts costing these days?

 

There's lots of sites that sell them. They range from $549-$600 though.
