That's sort of what I'm saying. N55s like your car sound different from the 335iS even with the same exhaust
. N54s and N55s just sound different. So I am trying to convey that if you have a stock 335is and rip out the stock exhaust and swap in the BMW PE, you will end up with a car that sounds 90% the same, at great expense.
