Hey guys just need your insight on something. I have a 335i n54 with stock exhaust. Im looking to purchase the 335is mufflers with the black tips. How much of a difference will that make compared to stock and the performance exhaust?

The 335is exhaust isn't the same as the PE (performance exhaust), contrary to what many people say. I have a 335is. It will be a nice noticeable upgrade from the standard mufflers, but depending on how much, you might as well pay for the PE. Or even the "PE exhaust mod". Cut open stock mufflers. Remove some packing material, replace perforated pipes with sealed pipes.
