Quick one, does the M20b20 have a single or double pipe exhaust? I have a Sportex silencer here that has single entry but the part number refers to an M20b20 with single pipe. I was under the impression all M20 engines had twin pipes? Can some one clarify?
TIA
M20 exhaust

My 1986 320i has a single pipe.
