Magnaflow has a 5" kit but it is still not 5" all the way from the turbo...

A down-pipe is a great addition, it lowers egt's help allow the turbo to spool quicker and gives you a deeper exhaust note.

It won't, the only companies making a replacement downpipe are MBRP and Diamond Eye. If you have any questions at all give me a ring.
