There are few members have these DPs on their cars. The ones I talked to said there’s no issues with them. You can find them on eBay at a good price. I was going to purchase them myself, but I found a good deal on used catted AMS downpipes on this forum. AMS DPs are 300 cell, BBMR are 200 cell, and stock I think are 400.
