RSR exmag or Apexi WSII which of the two has better/more airflow and generates good power, and/or look stock at the same time, i currently have Apexi n1, im tired of the angled exhaust and obvious modified look of it, i want to either go RSR or WSII, which of the two should i go with that will put out more airflow or put out as much air flow as the apexi n1 that i currenty have, and i want to drop my car lower but my apexi n1 wont allow me to , thanks!!

 

It's a toss-up. Pick one.

 

damn, well i got a 2.5 piping all around and if I go with the RSR, will i be loosing power? i assume the inlet is smaller then 2.5? unless im wrong? which looks better too in your opinion?
