1997-2004 Billy Boat Fusion SS Exhaust System with Quad 4 Inch Round Tips

With unparalleled performance, sound and style our 1997-2004 Corvette Billy Boat Fusion Exhaust brings NPP technology to your C5.

The Fusion is a bi-modal Exhaust System, meaning it has two passages, or modes, that the exhaust can travel through the muffler. Each of the mufflers has two outlets, with one side having a butterfly type valve which allows the exhaust flow to be shut off, regulating which side of the muffler the exhaust flows. One side of the muffler is the "quiet" side, and one side is the "loud" side. The "quiet" side is a smaller, muffled and chambered tube, while the "loud" side is 3" tubing straight through.

The butterfly is controlled by a vacuum valve, which was built and developed completely in house. On the Z06 and the 2008 C6 Corvette with the NPP option, this valve is controlled by the ECU. The valve opens based on RPM and throttle position. Since the C5 Corvette has no option for the valve, we use the same vacuum kit and control as the C6 without NPP. The expertise at B&B is getting the "tone" right for your C5 Corvette, and we think they nailed this one. In the closed position, the tone is agresssive, but substantially quieter than the standard Bullet system. Open the valves, the overall volume and tone increases to the point of the classic Bullet exhaust tone.

FAQ’s concerning Billy Boat Exhaust Systems, Names and Tonal Evaluations

How do I make a decision on the type of sound I want for my Corvette Exhaust System?

 

Since an exhaust sound is heard somewhat differently by each person, we have attempted to classify all BBE exhaust notes by a Style Name that identifies the attributes of that specific system.

 

     FUSION Exhaust - NPP Controlled Bi-Modal - Aggressive when Open, Mild when Closed.

     PRT Exhaust - Aggressive Sound at Wide-Open-Throttle, Mild sound at cruise.

     BULLET Exhaust -  Aggressive Sound

 

 

What is a Fusion Exhaust System?

 

Billy Boat Exhaust has designed a Fusion NO-DRONE exhaust for the factory NPP and the non-NPP Corvettes. On C6 Corvettes with the NPP option, the butterfly valve in the exhaust is controlled by

the ECU. The valve opens based on RPM and throttle position. The expertise at BBE is getting the “tone” right for your Corvette, and we think they nailed this one.

 

Even in the closed position, the tone is deeper, louder, and more aggressive. Open the valves and the overall volume and tone increases to the point heads will turn when you drive up.

 

Add our 648-042 conversion control 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.

 

 

What is a PRT Exhaust System?

 

The Billy Boat Exhaust PRT C6 exhaust system is the latest control in Performance Resonance Technology from BBE. Completely redesigned and reengineered for the C6, 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.

 

 

What is the meaning of a Bullet Exhaust System?

 

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 Exhaust System has quickly become the industry standard for a deep, aggressive muscle car sound for Corvettes.

 

You can see up to 18 rear wheel horse power and 17 foot pounds of torque from the Bullet. Billy Boat Exhaust’s boldest tip style and configuration insures the Corvette will scream “muscle car”.

 

What is a Cat Back Exhaust System?

The term “Cat Back” can be defined as the section of the exhaust system that runs from the outlet of the catalytic converter to the exhaust tips. A cat back exhaust system usually includes the pipes from the converter to the mufflers, the mufflers, and the exhaust tips.

A cat back exhaust is typically made up of rear-pipes, resonators, mufflers and a “style” and size of muffler tips. Depending on your Corvette’s year, model and location of catalytic converters, it can also include a mid-pipe and or a X-pipe.

 

What is an Axle Back Exhaust System?

The term "Axle Back" or rear section exhaust implies the exhaust system is located behind your Corvettes rear axle.  Corvette Axle Back Exhaust Systems typically replace the factory rear exhaust pipes, rear mufflers and muffler tips with an improvement in overall sound and appearance.

If the stock cat's can flow a large amount of exhaust gas without creating too much restriction, adding an aftermarket  "Axle Back" exhaust system should offer a nice increase in horsepower.
