I have a 2006 GT and I was considering replacing the mufflers with a after-market axle-back kit....my question is, if I do swap the mufflers, do I need to buy a Diablosport Predator(or something similar to it) to reflash the computer because of the muffler change? Or will the car's computer be able to make the needed adjustments?


Thanks

No tune needed for a muffler replacement. They don't make enough difference to matter to the PCM

 

Because I noticed that if you buy DS Predator from Steeda, it supposedly has a program for after-market mufflers......

 

Not necessary.

 

Nope.
