I'm pretty sure I'm going to replace my stock mufflers on my 05 GT with this: Pypes Pype-Bomb Axle-Back Exhaust (05-10 GT, GT500)
How important is it for me to order the optional exhaust Hanger kit that they offer with it?
Thanks

 

Also- if it matters, it's the muffler delete set up....

 

I would guess the optional hanger kit is for if you have a v6.
