Important Exhaust Notes
This MBRP Race Profile axle-back is built for C7 Corvette Grand Sport models originally equipped with factory NPP exhaust. It is the aggressive muffler-bypass version, not the quieter Street Profile system and not the Active Profile valve-retaining system.
The valve motors are reinstalled and plugged back in, but the MBRP Race Profile system does not contain functional exhaust valves. Factory quiet and loud exhaust modes are not retained. MBRP notes that tuning may be required. After installation and the first heat cycles, recheck clamps, wiring, clearances, and carbon-fiber tip alignment.
