..JSHIFFER2...you mention a crack in the muffler will cause an incorrect exhaust back pressure which then cannot be compensated by the electronics & the engine light may come on.A lot of M3W owners have removed the cats & baffles from their exhaust systems.As a result has anyone had the light come on,& any corresponding uneveness in the running of the engine??
Didn't he mention that light came ont with just one cracked manifold? Adding that when the other cracked it went out, suggesting it doesn't like an imbalance.
