What is this? Gt500 Corsa sport or Corsa xtream?
 

Hey guys,

I'm buying a set of used of what I thought was 2014 gt500 Corsa sport until I saw the picture of the mufflers. The person I'm buying them from claims they are indeed the sport mufflers. The picture below is the muffler the seller has it looks different from the corsa sport images I've seen online. Was anyone know if there were a design change or something?

What do you guys think?
