Is it illegal to remove the resonator?
Yes, you cannot remove something from the exhaust, whether you get pinged on it or not is a different question entirely. Technically you may be able to argue that the emissions have not been efected and the sound doesn’t exceed the perscribed levels, but AFAIK you can’t remove things.
What happens if I delete my resonators?
Three main benefits for removing exhaust resonators are to make your vehicle lighter, to give your engine a louder tone, and to get a slight increase in your horsepower. Since resonators help reduce the engine sound, when removed, your truck or car will sound like a muscle car, emitting much louder and obnoxious tone.
Does removing exhaust resonator void warranty?
No the modification does not void the warranty. If you modify the exhaust by removing the resonator and then the muffler cracks, or a hanger breaks off, they can not void the warranty, and if they try, they need to prove that the damage resulted because you removed the resonator.

Will a resonator delete throw a code?
Because the resonator delete is part of the back end of the exhaust system, removing the device can sometimes impact the performance of your catalytic converter. When that occurs, you can sometimes trigger a check engine light warning or a code in your system because there are backpressure changes that occur.
Will a resonator delete fail emissions?
