$1000 for a couple horsepower, deletes your factory resonator which is an excellent design, and doesn't even remove your secondary cats which will easily yield better gains alone then the whole PE exhaust.
Now replacing your secondary cats with two resonators along with the PE exhaust would be one of the best 328i sounds period.
