Those are SDs, some people have issues with the flex section leaking, I've been running mine for almost 2 years with the stock flex. Some people have some issues with them leaking at the slip joints, just use some copper rvt there. Some people have issues with the front 02 hitting the firewall.

What about the downpipe, I know SD does not offer this so would I have to use my stock one or order on from ZZP?
