I am selling an OEM section 1 with catalytic converters for 2001-2006 BMW E46 M3.
It was a super low mileage OEM 2006-2008 BMW Z4M section 1 that I modified to fit E46 M3. Length and flanges orientation was different so weld it to fit E46 M3. Also add O2 sensors bungs and an EGT bung.
Now it's basically the same as E46 M3 Euro section 1 but less restrictive cats
Price: $1600usd shipping included
