Yes - by PE I was referring to the performance exhaust. I installed that about a week after I got the car - When I bought my 135i in November of 2010 they didnt have a performance edition or even the PPK available.
I also installed he performance suspension and I am super happy with that as well, if anyone is considering suspension upgrades to go along with the bump in power.
