Thanks for the info, also does anyone have any ideas about down pipes with an electric cutout. QTEC down pipe claims to gain 21 whp, and 24 pounds of torque, and i think it sounds awesome. Below is a link to the their web site, which has a demonstration video of the down pipe on an 03 WRX. Let me know what you think.
