Are the b5 s4 exhaust (w/ downpipes) the same as Audi a6 c5 2.7t?
 

I have a 2000 audi a6 c5 2.7t and I want to purchase downpipes and a full turbo-back exhaust and I found ssautochrome and i've heard both good things and bad but I want to know if these products would fit my 2000 audi a6 2.7t? I was hoping that at least the downpipes would fit... take a look please and let me know
