None of the 2010 exhaust axlebacks are a direct bolt on for the 2011's. They changed to a ball and socket type fitting instead of slip fit. That being said if you want to cut up your exhaust they will work.
"Nope." They exhaust on the 2011 is different. I wanted to take mine off my 2007 and put it on a 2011 (if I get one). I picked mine up at their "garage" sale a few years ago, for an incredibly cheap price (tiny scratch)...of $75.
Not sure I'd want to cut up a new '11 exhaust, but if the surgery was minimal, I'd do it.
Yeah i also called roush last week and they said it is a whole new set-up for 2011. They said they were producing the 2011 cat-back's and should be on sale in about a month or two.
