* Increased noise: The resonator is designed to dampen sound. Removing it will make the exhaust significantly louder, potentially exceeding legal noise limits in your area. This could lead to tickets.
* Drone: Resonators help mitigate drone, a low-frequency rumbling sound that can be very irritating, especially on long drives at certain RPMs. Removing it will likely increase drone.
* Emissions: While less likely to be a significant factor, removing the resonator might slightly affect the exhaust system's backpressure, potentially impacting emissions (though probably not enough to fail an emissions test in most places).
* Possible legal issues: Depending on your local regulations, modifying the exhaust system could be illegal.
In short, you can remove it, but the trade-off is significantly more noise and potentially drone, and you might even face legal consequences. If you want a louder exhaust, it's generally better to replace the entire system or muffler with an aftermarket option designed for that purpose, to maintain some level of sound control and avoid potential issues.
