In my
limited knowledge on this, the only way an exhaust can have that much of an impact is if the 02 sensors got messed up somehow during the install and the car is running very rich. However, someone can keep me honest on whether the mid section of the 86/BRZ does indeed have a "monitored" sensor for it to have this much of an impact.
