Chevy C8 Corvette Stingray Bullet Exhaust System #FCOR-0786 Black Speedway Tips *WITH AFM VALVE*

An enormous amount of time an energy has gone into the development of our new C8 exhaust line.  We have taken everything we have learned over the last 30 years in the performance exhaust and racing industry and put it into the design of the exhaust for the C8 Corvette.  This is my personal car, as I wanted to be sure we devote the proper time into development and testing to make a product that performs and meets the expectations of our customers.

As all of our exhaust, the product is 100% T-304 stainless steel and is fully TIG welded.  The Bi-Modal Fusion design of the system maintains all the factory NPP capabilities (eco, tour, sport and track mode) and uses our in-house manufactured NPP valve body.  We have taken great care to design this valve to exact factory specifications to ensure proper function and durability.  The exhaust flow pattern is split in a “Y” design, allowing a full 3″ exhaust flow when the valve is open and 2 1/2″ flow when the valve is closed in touring mode.

The exhaust note from the Fusion system is nothing short of amazing, with an overall deeper, more aggressive tone.  In the touring mode with the valve closed, the system is slightly louder than stock with a tone that is great for long drives and cruises.  In the sport or track mode, the full 3″ exhaust is engaged with more overall volume a much deeper note.  Under acceleration the exhaust will turn heads with a tone you have come to expect from a Billy Boat system.  The muffler utilizes our proprietary PRT design, which cancels any resonation which may develop in either open or closed mode.

The system is designed to mount the Active Fuel Management valves in the factory location and does not affect the car going into 4 cylinder mode.  We have deleted the valve AFM itself, and with the PRT design the system does not resonate in 4-cylinder mode and does not set off a CEL.  This was a concern in the design and testing of the exhaust, as we know from the C7 that the exhaust note in 4 cylinder mode required the AFM valve.

The C8 exhaust is standard with 5 heat shields that protect the trunk area and engine bay from excessive heat.

The exhaust will be available in three tip styles ( 4.5″ carbon fiber , 4.5″ polished stainless, and a Speedway tip  designed around the shape of the valance much like the C7.  The stainless and the Speedway will also have an option to be ceramic coated in black.

  • 4″ Quad ROUND Double-Wall Tips.
  • Mandrel bent from the highest-grade T-304 stainless steel.
  • Designed, tested, and manufactured to the finest hand-made integrity found in any exhaust system.
