1 Answer


any exhaust is specifically designed for the efficiency of the motor/system/setup, generally speaking. I don't know how much of your exhaust is now 3" (cat back?) but it can greatly alter the flow and fuel ratio and dynamics of the exhaust system. I would wait for expert advice from here or go onto impreza or NASIOC forums and ask for advice on tuning to fix this. Best regards,
