Billy Boat Exhaust axle-back for the 2017-2019 C7 Grand Sport with an automatic transmission and 2014-2019 C7 Corvette has a deep, aggressive muscle car sound and offers performance gains of up to 18 rear wheel horsepower and 17 ft lbs of torque.
To tone your Bullet Exhaust down a little, the PRT X-Pipe section with resonators will help to smooth out the exhaust pulses and still maintain an aggressive tone.
Note: fits a Grand Sport (automatic), but eliminates existing NPP functionality.
