anyone know how I can pass emissions with long tube headers? I keep getting a code that sensors have a slow response. the oxygen sensor rediness tests pass but the catalyst never does. any way to get around that without changing exhaust? I have a 99 cobra with an 04 cobra motor. tune is based off a stock 04 cobra tune. kooks long tubes with off road x pipe
I do understand that it is doing that because the o2 sensors are located farther back and the computer is expecting readings with them closer to motor.
