I am trying to replace both flex pipes before the cats on my Audi A4 2.8L 12. The existing pipes are leaking quite a bit and I was not sure which replacements would be the best fit.
I read over a lot of forum posts about this exact issue. I just wanted to get a second opinion on 2 things.
1. What size is this pipe on the 12valve quattro? My guess was 50mm.
2. If thats the case, will this be my best bet: http://www.ebay.com/itm/300511490735...#ht_500wt_1038
3. Also, where could I get new collector gaskets for this car? I'm guessing ill be taking down the downpipe to make sure I get a good bead all around the new flex pipes.
