Precision crafted using 100% T-304 stainless steel and mandrel bending, this exhaust system is manufactured as a direct bolt-on replacement for the factory system. By utilizing the factory mounting locations this system requires absolutely no cutting, welding, or modifications for installation. All Billy Boat Exhaust systems for the C5 come complete with mounting hardware and are direct replacement for stock exhaust systems. Attention to detail in manufacturing means easy installation. No machining. No down time. Just a faster, better sounding, better looking and more muscular Corvette right out of the box. Guaranteed for life against corrosion, rust or burn through and two years for materials and workmanship.
The Billy Boat Exhaust PRT after-cat system employs exhaust technology unique to the aftermarket. So unique, in fact, it doesn’t use a muffler at all. The Billy Boat Exhaust PRT system is simple in design, though more complex in theory, which suggests that you can have a mellow 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, while a mellow sound is emitted at cruising speeds thanks to the unique Purge Chamber. This Billy Boat Exhaust PRT system works purely on physics without mechanical devices to direct exhaust flow.
Using our in-house Dynojet chassis dyno on a 2001 6-speed with a Billy Boat Exhaust PRT system show gains of 12 additional horsepower and 14 lbs/ft of torque. What’s cool about the Billy Boat Performance Exhaust PRT system is it’s decidedly Dr. Jekyll and Mr. Hyde nature. You can cruise down the highway, in overdrive, at extra-legal speeds and be totally unaware of the monster that lurks beneath. Hammer the throttle and the beast is awakened, roaring like AJ Foyt on too much caffeine.

What’s the difference between our exhaust systems?
BULLET – Aggressive Sound
Billy Boat Performance Exhaust has created the most aggressive C5 performance exhaust system to be released – the Bullet! Not for the meek or mild, the Bullet has quickly become the industry standard for a deep, aggressive muscle car sound on the C5. You can see up to 18 rear wheel horsepower and 17 ft lbs of torque from the Bullet. With Billy Boat Exhausts boldest tip style and configuration insure the C5 will scream ”muscle car”.
PRT – Aggressive Sound at Wide-Open-Throttle, Mild sound at cruise
The Billy Boat Exhaust PRT after-cat system employs exhaust technology unique to the aftermarket So unique, in fact, it doesn’t use a muffler at all. The Billy Boat Exhaust PRT system is simple in design, though more complex in theory, which suggests that you can have a mellow 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.
ROUTE 66 – Moderate Sound
Cosmetics on the Route 66 are drastically improved with Billy Boat Exhaust’s exclusive quad 4.5″ wide and 3″ tall, rolled edge tips. The C5 Route 66 System creates a distinctive muscle car idle note that emits a true touring performance sound on the highway and will garner an additional 11 rear wheel horsepower.
How a Dyno Works
We’re going to quote DynoJet directly to explain how the machine works, since paraphrasing would only do you an injustice. “Power, in mechanical terms, is the ability to accomplish a specified amount of work in a given amount of time. By definition, one horsepower is equal to applying a 550-pound force through a distance of one foot in one second. In everyday terms, it would take one HP to raise a 550-pound weight up one foot in one second. So to measure horsepower, we need to know force (in pounds) and velocity (in feet per second). DynoJet’s inertia dynamometer measures power just in this way. The dyno calculates velocity by measuring the time it takes to rotate the heavy steel drum one turn. The dyno measures force at the surface of the drum by indirectly measuring the drum’s acceleration. Acceleration is simply the difference in velocity at the surface of the drum from one revolution to the next. The force applied to the drum is calculated from acceleration using Newton’s 2nd law, F=MA, (F)orce equals (M)ass times (A)cceleration. Power is coupled to the drum by friction developed between the driving tire of the vehicle and the knurled steel surface on the drum of the dynamometer.”
“When an object rotates around a point, the object’s speed of rotation depends on both an applied force and the moment arm. The moment arm is the distance from the point of rotation to where the force is being applied. Torque is the product of the force and the moment arm. For example, think about trying to spin a drum by wrapping a rope around the drum and then pulling on the rope. If the rope is wrapped around a drum of one-foot radius and pulled with 550 pounds of force, the resulting torque is 550 foot-pounds. The torque on the dyno’s drum can be calculated by multiplying the force applied by the drum’s radius. However, engine torque is not equal to the dyno’s drum torque because the gearing through the drivetrain changes the moment arm. The change in the moment arm is proportional to the ratio of engine speed to drum speed. Therefore, tachometer readings are necessary to calculate and display engine torque.”
