I just installed a new axle-back. Do I need a tune?

Axle-back exhaust systems just affect the muffler region of the exhaust. This means that the new parts are clear from any sensors or meters that the ECU (Engine Control Unit) may need to run the vehicle. They may let more sound flow through, but AB systems do not affect the aspiration of the engine.

As a result, Axle-Back exhaust systems do not require an updated tune.
