Well im just asking because i know a guy selling a s4 downpipe but i dont know if it will fit let me knw thank you.

Yes, it's the same set up. It's just the body and the frame that are different.

its not the same set up but you can get it to work if you modify it. The A6 Dp's are different length and inlet size. If it is from a 6 speed and you are a tip then you run into further issues. You can get it to work but it is not a direct bolt on, There will be some modification needed

thanks. i just might do the down pipe mod with drilling out the inside.

ya the Dp's are different.

I'm a huge fan of the piggie dp's as they have worked for me.

as for doing it your self deffinitly a word of caution. I have seen several others say the same thing and it SEEMS to me every time some one says that there is a post 2 months later about problems they are having and there CEL is on

I my self tried to make them. about 45 min later all I had was a big mess and a cat that was barrly removed. not only that but I would have had to move the o2 bung and weld it in just the right spot.

just sent my friend to vast (who makes the piggies) for the money I feel it is not worth the headache...I'm a huge cheap a$$ and I think it is still worth it to have them do it.
