The MRT Street Race Resonator Delete Exhaust system not only gets rid of the huge stock resonators - it will give your Challenger the "move over" attitude it needs to get noticed. This option is a surprisingly simple and easy way to upgrade your Challenger without replacing the full exhaust system like splurging for new mufflers or an h-pipe. With this simple swap, the MRT Street Race resonator Delete adds a deeper, performance rumble and opens up the internal diameter of your system to increase exhaust flow. This mid-muffler deleted system is handcrafted in corrosion-resistant T304 stainless steel and is a 3 inch straight pipe. The resonator delete option also reduces the weight of your vehicle, boosting your fuel economy and acceleration from a better power-to-weight ratio.
For customers with factory-installed Active & Dual Mode Exhaust valves, MRT offers and recommends a simple solution that allows you to upgrade your exhaust system without having to develop a tune. For more information on these plates, refer to
