I was trying to order a Borla cat back this morning but all Borla shows is 09-10 model. I called them and they said they cant guarantee it to fit and returns have a 25% restocking fee. They said they will be testing it but it could be weeks to months before I will know for sure. I said I would be happy to be there guinea pig if they would wave the restocking fee, he didn't seem to want me to be part of the team hehe. Anyways.. Would anyone know if any mods to the exhaust was done between '10 and '11 models? Thanks.
