Since I'm going top-mount I won't be needing this anymore either. Just like the title says, it was used for 20k miles. I'll include the fat O2 as well, which also has 20k miles on it. Looking for $225, these retail for $400. Absolutely nothing wrong with this downpipe, and gives you the most ground clearance a DP will allow. It's flush with the frame rail on my car and has a 1/8in of space inbetween the body and the top of the DP.
