Thinking about a custom 3" exhaust

Mino

Hey guys I was thinking about doing a custom 3" on my Z I just got as soon as break it in at 500 miles already . I was speaking to my muffler shop about it he said he could do it (Mike's Muffler in El Monte California) a lot of guys here know him one of the best in the SoCal. So here is my question I want to do a 3" full exhaust except oem Y pipe and cats which I will be getting some berk HFC soon. He told me he can put something together, however I was thinking about buying the mufflers myself, I have a few in mind I was wondering if any of you would recommend me one from experience. HKS hi power Carbon version, Greddy Ti-C (just mufflers) Apexi N1, or any suggestions?

Or should I just get a Agency power exhaust with the test pipes and be done with it lol.
One last question what do you guys think of a single exit instead of a duel on our cars good or bad idea? I know this one is just an opinion just want to see what you guys think.
