Got this question by someone who is not registered here yet. As I do not own an E34, I post the details here, maybe the E34 experts can clarify that:
Will an E34 M50 sedan OEM exhaust fit an E34 M50 Touring ?
I live in Canada. I’m having a surprisingly difficult time locating an exhaust system (catback) for my car. I have researched for two weeks, without discovering a clear answer. The VIN is WBAHJ631XNG E34 M50 type code HJ63, prod. date 04/1992. RealOEM shows center muffler 18121427802 which supersedes 181217286 ,rear muffler 18101705761 which supersedes 18121427800, 18121744126, and 18121728625
Numbers for the sedan, same month of production are one 1 number up : center muffler 18121427801, Rear muffler 18101705760 .The Catalytic converter numbers also differ by one between the touring and the sedan :Touring : 18301728616, Sedan 18301728417
However the gasket ring sizes for the coupling between the cat and the center muffler are identical for both sedan and touring : 47 mm on the driver side tube and 50 mm on the passenger tube , which suggests that the diameters are the same. The flange for the coupling has the same part number for both sedan and touring as well.
Bottom line : I can locate the OEM (Eberspacher) exhaust in the US for the sedan but not for the touring. Are they the same ?

i can tell you that an e34 M5 sedan exhaust fit's an e34 m5 touring, despite slightly different part numbers. From that i'd think a m50 sedan exhaust should physically fit a touring with same engine.

Sedans and Tourings are identical ahead of the B-pillar and under the floor. The exhaust will fit.
