I just read that the best setup would be to use the WRX blowoff valve/valves if your going to run twins. According to the post they flow much more cfm due to the exhaust valves 23 degree angle and dual spings. Not only that, but instead of the traditional pshhhhh sound, this one makes a pshhhhhoff sound. Much cooler!
