I traded my Audi S4 b8.5 and purchased the new 2018 Audi S4. Unfortunately, the exhaust doesn’t fit and I just got this catback few months ago. Drove on it for less than 1,500 miles, nothing. Anyways the exhaust looks new. I purchased the AWE catback in May paid $1637.95 with tax. I added the Silver tips 102mm which cost more. The IE downpipes were purchased a month later in June they cost me $699.99 plus tax. Let me know who’s interested and how much they can offer me thanks. Pickup only in Illinois.
