I think the E46 330 rear section can be modified too. Have to check my manual where I have all that compiled... |
Specifically, all E46 M54 and Z3 M54 (2.5 and 3.0) systems are twin pipe. All E46 M52tu are single pipe. All of these systems are one piece from the manifolds to the tip.
ZHP aside, all E46 M54 systems are the same.
All E46 M52tu systems are the same.
All Z3 M54 systems are the same.
All Z3 M52tu systems are the same.
The Z3 M52tu also has a one piece system that is single pipe. The M52 Z3s have a single pipe system that is 2 pieces.
All M52tu and M54 cars have the cats in the exhaust manifolds and M52/S52 cars have the cats in the mid section.
