So i have a 2004 wrx wagon with an axle back delete exhaust and am about to run a cobb v2 accessport and i was gonna run stage 2 but it says that you need turboback exhaust to run stage 2. I am just out trying to find out if i can still run stage 2 with an aftermarket intake. my exhaust is basically off from 1 1/2 feet from the cat. I will have full turboback catless exhaust in the next couple months. I want to know if it is safe to run stage 2 until i get the exhaust.
