What muffler offset should I get? Help!

[Quick]

I'm in the process of ordering a Flowmaster 50 series muffler.

I'm getting single in, single out. What type of one should I get.. and I mean what type of offset (if any).

Let me know.. thanks

if you are getting custom pipes out the back than it really shouldnt matter. mine is offset in center out
