I called my contact at MagnaFlow about the Dual Core, Universal Muffler XL Turbo Series, part # MF13743 for your 460 motor.
They told me it will increase the horsepower and torque from 2 to 5 percent. It will not affect the catalytic converter lifespan, and will not affect the 02 sensors in any way. The gas mileage change has not been tested so they were unable to tell me if it would be affected.
This is a weld-on installation. the inlet and outlet diameter is 3 inches. view full answer...
The MagnaFlow Cat-Back Exhaust System # MF19190 is going to be louder than the stock exhaust on your 2017 Jeep Grand Cherokee and I'll send you a link where you can hear what it will sound like when installed on your Jeep.

The Cat-Back Exhaust System is constructed of 100 percent stainless steel... view full answer...
It is easiest (for me!) to think of engine intakes, exhausts, resonators, etc. as parts of the vehicle "respiratory" system. After all, in a way an engine is simply an air pump; it "inhales" air and "exhales" exhaust. Changing any part of this system will tend to either increase or reduce the engine's ability to mix air and fuel.
Power and torque are a result of air/fuel combustion and a new exhaust for instance that allows the engine to more freely release exhaust can allow better combustion... view full answer...
