Technically, no, a resonator delete will not void your Hyundai warranty, thanks to the Magnuson-Moss Warranty Act. That said, if you perform a poor resonator delete that results in rusting or other damage to your muffler or exhaust system, it could void the warranty because your mod directly resulted in the damage. That’s why it’s important to consult the experts at your local Hyundai dealer, garage, or muffler shop to have the delete performed correctly.
A quick caveat—while your warranty will still be intact, the resonator is technically a part of your emissions system, so removing it may result in failing an emissions inspection.
Removing your resonator is going to not only change your engine sound but also lighten your vehicle’s weight, so your sporty Hyundai is going to have that much more pep. Make sure you’ve got yourself covered with solid car insurance just in case you have trouble resisting the temptation to see how your mod affects your car’s performance.
