Billy Boat Exhaust: 2005-08 CHEVY C6 CORVETTE PRT AXLE BACK EXHAUST SYSTEM (ROUND OR OVALTIPS) Billy Boat Exhaust

The Billy Boat Exhaust PRT C6 exhaust system is the latest in resonance control 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 crisp, clean, noticeable sport note when you’re tearing up the streets. The PRT comes complete with a true straight-through exhaust passage under aggressive driving conditions, though a mellow sound is emitted at cruising speeds thanks to the unique Purge Chamber.

The fact that the PRT C6 exhausts do NOT have that unpleasant DRONE was the most popular aspect of our Purge Resonance Technology. This was usually shared with an appreciation of how you (or whoever’s driving, really) have so much control over your C6 exhaust system, both in sound and in the correlating performance and driving experience.

Because we’ve been so closely connected with Corvette excellence, we aim to show our dedication by putting our absolute best into every hand-made–never outsourced, always in the United States, stainless-steel C6 system that we make.

• 4″ Quad ROUND or 4-1/2″ OVAL 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.
