Billy Boat Exhaust sets the pace for stainless steel exhaust systems, especially when it comes to Corvette exhaust systems. All of our Corvette exhaust systems are built by hand using T304 stainless steel. Through extensive dyno testing we concluded that the LT motors love to breathe, so we designed the entire system using 3″ mandrel bent tubing. With a uniquely designed resonator and muffler pair, your L Tl, L T4, and ZR 1 motor will increase in performance and sound.

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.” Calculating Torque “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.”

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- It helps to do this installation on a lift if you want to get the factory mufflers out in one piece. #2- Unbolt the flange and loosen the clamp that holds the front of the system. #3- Remove the factory nuts from the rear of the mufflers and set aside. Loosen the brackets that hold the rear of the mufflers and let hang in place. Remove the bolts that hold the center section of the system. Save the bolts as they will be reused. (NOTE: If the vehicle is a convertible, the center x-frame will have to be removed to remove and install the exhaust system). #4- Remove the existing system. #5- To install the B & B system align the drivers side and passenger side front pipes and loosely tighten the supplied clamp and the reused flange bolts and nuts and reinstall the existing hanger bolts. #6- Slide the center section onto the front pipes and loosely tighten the supplied clamps. Slide the drivers side and passenger side rear pipes onto the center section and loosely tighten the supplied clamps. Reinstall the existing hanger bolts. #7- Position the new mufflers into place by inserting the mounting bolt at the rear of the muffler into the factory hanger. Mate the extension pipe and muffler inlet with the supplied clamp and just tighten them enough to still allow for movement while aligning the system. *But do not tighten them completely. Install the existing nut onto the mounting bolt at the rear of the muffler. #8- With all components in place, use a straight edge along the bottom of the tips for proper alignment. Keeping in mind that it will take some time to align them correctly. #10- Then start by tightening the flange and clamp in the front of the system first and then the clamps connecting the muffler sections making sure everything is still in alignment. Finish by tightening the existing brackets and the existing nuts at the rear of the mufflers. #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.
SAFETY: Appropriate disassembly, assembly methods and procedures are essential to ensure the personal safety of the individual performing the kit installation. Improper installation due to the failure to correctly follow these instructions could cause personal injury or death. Read each step of the installation manual carefully before starting the installation.
VEHICLE SUPPORT WARNING: Should the purchaser decide to install this exhaust product at home, be warned that car or light duty truck/van “bumper” jacks are intended for emergency use only. The use of frame contact jack stands in conjunction with a floor jack as main support is highly recommended to minimize accidental dropping of a vehicle while the installation proceeds. We recommend the use of a shop hoist if possible. Please use caution!
