1990 300E, 2002 ML500
I am thinking of having the exhaust resonator, beneath the driver's seat, removed for Father's Day on my dad's ML500. How loud will it make the exhaust, will it be something like a stainless steel exhaust sound or a glasspack exhaust sound? Will it mess with any of the settings or sensors? Will it mess with the ability to pass inspection? How much should it cost?
