Hello, I have a 2017 mustang ecoboost and I'm planning on taking out the mufflers and running pipes to the tips. Will I need a tune after doing this? Or will the ecu adjust for the reduced back pressure? I really want to make this car last forever.
Just watch out for cops. In about 90% of the USA, this violates local and/or state noise ordinances I know for a fact in Texas repeat violations will get your car impounded and release from said impound will require you to do something to silence the exhaust...
