This Bullet-PRT is a single mode exhaust designed for Corvettes without NPP.
The Bullet-PRT is the most aggressive performance exhaust system to be released and has quickly become the industry standard for a deep, aggressive muscle car sound. Your C7 can see performance gains of up to 18 rear wheel horsepower and 17 ft lbs of torque from the Bullet.
If you want to tone your Bullet down just a little bit, a great option is the PRT X-Pipe section with resonators. This will help to smooth out the exhaust pulses and take the edge off the Bullet while maintaining that aggressive tone.
*Fits a Grand Sport (automatic), but eliminates existing NPP functionality.

What’s the difference between our exhaust systems?
FUSION Exhaust – NPP Controlled Bi-Modal…Aggressive when Open, Mild when Closed
Billy Boat Exhaust has designed a Fusion NO-DRONE exhaust for the factory NPP and the non-NPP C7 Corvette. On C7 with the NPP option, the butterfly valve in the exhaust is controlled by the ECU. The valve opens based on RPM and throttle position. Our expertise here at BBE is getting the “tone” right for your Corvette, and we think we nailed this one. Even in the closed position, the tone is deeper, louder, and more aggressive. Open the valves, the overall volume and tone increases to the point heads will turn when you drive up.
*Add our FCOR-0468 conversion kit for Corvette models without factory NPP controls. The kits comes complete with all the wiring, remote switch, vacuum line, vacuum accumulator, and vacuum switch needed for installation. Can only be ordered with Fusion Exhaust Systems.
PRT Exhaust – Aggressive Sound at Wide-Open-Throttle, Mild sound at cruise
The Billy Boat Exhaust PRT C7 exhaust system is the latest in resonance control technology from BBE. Completely redesigned and reengineered for the C7, the system is simple in design, though more complex in theory. You can now have a mellow NO-DRONE sound at cruising speeds and a sport note when you’re tearing up the streets. It allows true straight through exhaust passage under aggressive driving conditions, though a mellow sound is emitted at cruising speeds thanks to the unique Purge Chamber. Designed especially for the automatic, paddle shift and cars with headers, this Billy Boat Exhaust PRT system works purely on physics and adrenaline. Increases of 15 hp and 14 ft lbs over stock.
BULLET Exhaust – Aggressive Sound
Billy Boat Exhaust has created a deep, healthy exhaust note at low RPMs with an assertive muscle car roar on acceleration. Not for the weak at heart, the Bullet has quickly become the industry standard for a deep, aggressive muscle car sound on the C7. You can see up to 18 rear wheel horse power and 17 ft lbs of torque from the Bullet. Billy Boat Exhaust’s boldest tip style and configuration insures the C7 will scream ”muscle car”.

With proper installation, your new Billy Boat Exhaust system will last a lifetime. While installation of this product is very simple and straight forward, there are a couple areas that need some attention.
#1- Secure vehicle to wheel lift.
#2- With the car safely lifted and chocked, remove the 22 bolts securing the aluminum plate that covers the X-pipe and set the plate aside.
#3- To loosen the rear fascia remove the six bolts located on the bottom rear of the vehicle. Then remove the two bolts located in the window that the tips reside in. Pull gently on the center (place both hands on opposite sides of the tip window) of the rear fascia until the clips release.
#4- Unbolt the flanges located at the front of the factory center pipe. Then remove the bolts that hold the rubber hanger mount located at the rear of the center pipes. Loosen clamps on rear of center pipe. Pull center pipe back off the donuts at the front of the exhaust system. Lower center pipe down and pull forward off the front of the mufflers and set aside.
#5- Disconnect actuator wires from actuators. (Depending on the model of the car there are either 2 or 4 actuators. Non-NPP systems have 2.) Loosen and remove bolts that hold the muffler cans together. To remove the mufflers, unbolt the rubber hangers from car then pull the hangers through the rubber mounts and lower the mufflers down and unwrap from over the axle. You may have to move the mufflers to one side or the other to get them out. (When removing the mufflers, have another person pull gently on the rear fascia to provide enough space to pull the mufflers out.)
#6- Remove stock actuators from stock system and secure to your new Billy Boat system along with rubber hangers from stock system. (Loctite is advised but not required to secure the bolts in actuators to ensure a secure fit.)
#7- Position the new muffler/axle hoop system into place. Then insert the mounting hook into the factory rubber hanger. Mate the muffler/axle hoop system to the center pipe (Billy Boat X-Pipe if used) in the reverse order of removal and just tighten them enough to still allow for movement while aligning the system. *But do not tighten them completely.
#8- With all components in place, align the tips and once you have achieved the alignment tighten the bolts that hold the cans together. Keeping in mind that it will take some time to align them correctly.
#9- Then start by secure the bolts that hold the X-pipe then tighten the flanges in front of the system first and then the nuts, bolts and clamps connecting the muffler sections making sure everything is still in alignment.
#10- After the system has been correctly aligned, locate the rear fascia back into the clips and replace all of the bolts that were removed then re-secure the aluminum plate that covers the X-pipe.
#11- Fire the car up and take it for a spin around the block making sure there are no rattles.
#12- After logging on a few hundred miles re-torque your work.
