Custom euro-style section 1 for a Z4M. This is an original s-pipe off my 2007 M coupe that I have modified. I originally planned on using this for my car when installing euro headers, but I found an actual euro cat at the last minute. I bought the bungs from forum members, and my buddy welded them on. I had to cut off part of the heat shield to give the mig welder enough access, but then he spot welded the shield back on. It's ugly to look at, but I pressure tested it, and I could not find any leaks. If you are doing a euro header install, this is a cheap and effective way to re-route your o2 and EGT sensors.
