New Exhaust kit

[Bunta]

Hey guys im planning on buying a exhaust kit but i can't seem to find a good one.
Honestly i want the muffler to look stock (like the thermal), so I figured why not get a 3" Thermal Exhaust turbo back, but so far i haven't found a site that has a Thermal 3" downpipe. So I was wondering if I could get like a Apex'i N1 3" downpipe and then just attatch the Thermal 3" catback.

Or can anyone just help me out and let me know whats a good set up that helps a lot with performance and still keep that OEM type muffler.

thanks!!
