exhaust questions
 

Hi all. Hope everyone is tickety boo??
I have a widetrack sti and yesterday I noticed an exhaust blow just before the mid section box. Now is it best to get it repaired welded etc or new pipe? It is the standard exhaudt with prodrive backbox. Or shall I chuck it and get a stainless part? Although if I do this will I have to get a remap????!!!!! Argghhhh
Thanks for your responses :)
