All,

I've got a 10 Mustang GT with a C&L Street CAI. For now I also have the "no tune" calibration insert for the Mass air sensor in place. I'm thinking about adding the FlowMaster American Thunder Mufflers (17410) to the car. Without adding a tune, can I do this and not have any error codes??

The plan is to do the muffler swap and then go to Brenspeed and get the SCT tuner.

Thanks for any and all info.

No tune needed for new axlebacks/mufflers.

You can add the mufflers with no problems. And by the way I have a new set of these I will sell you for $200.00. PM me if you are interested.

When are you going to change that no tune required and unleash more power?

No tune required for anything beyond the rear O2 sensors.
