Hey guys.. Do I need to reste the ecu if I change the mufflers out to magnaflows? Will it make a difference, or is it unecessary?

 

i don't think you need to. but then every time you reset your ecu the car will run a bit faster anyway

 

yeah, some people do it everyweek.
But I a lazy.

 

It won't hurt to reset the ECU, but it might help because the ecu will adjust so it gets used to the more free flowing exhaust and your new driving patterns (I assume you'll probably be dipping into the throttle more to hear your wonderful new exhaust )
