MRT Engineering 14-19 Corvette C7 MRT QuadFlow Cat-Back - 91S121
The MRT Corvette C7 QuadFlow Cat-Back system has a loud, deep muscle car sound and is handcrafted entirely in corrosion resistant T304 Stainless Steel. Base systems include T304 polished SS 4" tips and 3" mandrel bent tube. A Black Ops tip finish is available for an additional fee (Black Ops is a high temperature ceramic coating in black matte finish). This system is engineered for the best sound to provide your Corvette with the perfect balance of performance sound in spirited driving - comfortable in highway driving and managed sound at low speed and idle. This exhaust variant has straight through design with the loudest exhaust note, versus the stock exhaust. This Cat-Back exhaust will give you improved performance and sound with minimal drone as well.
For Corvette customers with factory installed AFM / NPP devices, MRT offers and recommends a simple solution that allows you to upgrade your exhaust system without having to develop a tune to defeat the AFM. For more information on these plates, refer to
