I looked for this I think they are, just want to be positive. s4 turbo exhaust and s5 turbo exhaust are the same? Might as well go and ask if this is also true with the n/a's so someone can search it. O I want to add the word differences.

 

Yup.

 

Well good.

 

The only differences between any FC stock cat back exhaust system is the mufflers. The Coupe, Turbo, and verts all got their own dedicated mufflers.

But the cats and cat setups are slighty different between FC series.
