Slight breakdown on the right side.
This is the most significant area of catalytic material breakdown.
Selling a set of Milltek downpipes for the B6 S4 6spd. As I understand it, these will work on either a B6 or B7 but only the 6spd models. These are a couple years old and probably have about 25-30k miles on them. As you can see in the pictures the cats are showing some signs of initial break down. On one pipe the breakdown a very minor on the other it's more significant on one side. I had them on my car for about 10k miles. During that time the break down did not seem to worsen by very much, but despite that I am willing to part with these for the low ball price of $200 plus shipping (if you're not in the Boston area).
