You can try finding a used BMS DP. Or buy a new one from AR (expensive), VRSF (priced similarly to BMS) etc...

All catless DPs will throw a code.
- If you wanna go catless get a tune to "clear" the codes. JB4 or Cobb should do the trick and they both have a stealth mode if you are worried about your warranty.
- If you just decide you don't want a tune then get a catted DP, the gain in power is not as good as the catless though.
I have the AR Desing 4" catless DP with the BMW PE, couldn't be happier
My 2 cents
