C7 Corvette owners whose Corvette's did not come from the factory with the NPP option can now upgrade their Corvette's to include a functional bi-modal exhaust system. BBE's retrofit NPP exhaust system includes their butterfly valve system which can be controlled by remote switch opening and closing the valves as desired. Valves are operated by vacuum from the engine. Complete instructions are included for this NPP option upgrade. Designed for all 2014-2019 LT1 Corvettes that came from the factory without the NPP option.

The Gen3 Fusion exhaust for the 2014-2019 Corvette Stingray is the result of Billy Boat's extensive development over the last six years of NPP exhaust technology. BBE has learned a few things with their butterfly valves and now the C7 Corvette owner can take advantage of them in the new Gen3 Fusion systems. The result is a muffler system that provides a deeper, richer and more voluminous sound than the factory C7 Corvette NPP exhaust system.

The heart of the Billy Boat Fusion exhaust system is a combination of their exclusive PRT muffler coupled with their own 3" butterfly exhaust valves. The full stainless mufflers incorporate two passages through which exhaust can travel through. BBE's exclusively 3" butterfly valve, built into the mufflers, regulates the exhaust passage. Passage one is a muffled and chambered tube incorporating Billy Boat's exclusive PRT (Purge Resonance Technology) to eliminate drone at cruising speeds, while delivering deep and smooth American V8 muscle car sound.

Exhaust passage two is a straight through tube that allows more exhaust volume at idle, cruising and head turning acceleration. Sound volume is increased to adrenaline pumping levels, with increases in both horsepower and torque numbers. Heart pounding performance that is fully managed through the C7 Corvette's NPP system controls.

The BBE Corvette PRT exhaust system is manufactured from T-304 stainless steel system, using precision mandrel bends for uninterrupted flow for maximum performance.Satin brush finish with polished tips for a spectacular mirror finish that truly gives your Stingray Corvette the look, while the aggressive sound will have heads turning everywhere. Muffler tips are substantial 4" round polished stainless.

Check out these features of the BBE C7 Corvette Retrofit NPP Fusion Exhaust System:

  • Precision hand fabricated from CNC mandrel bent T304 stainless steel and TIG welded
  • Full 3" Exhaust Pipe
  • Features BBE's proprietary 3" butterfly valve at both front and rear of muffler for improved flow and performance (OEM uses 2.5" valves)
  • Includes vacuum connections, mild-to-wild switch and instructions for NPP style upgrade
  • Deep - aggressive exhaust sound
  • Maintains the factory butterfly valve and for 4 cylinder mode function
  • Made in the USA

All BBE Performance exhaust systems are precision built, completely TIG welded, and are a direct replacement for stock exhaust components including all mounting hardware. A perfect mix of performance, sound and style for the C7 Corvette Stingray. Each Billy Boat Performance Exhaust system is backed by a lifetime warranty against rust, corrosion or burn through and 2 full years against defects in materials or workmanship.
