LMPerformance is proud to handle B&B Performance Exhaust systems. Since 1989 Billy Boat Performance Exhaust has designed, tested, and manufactured the highest quality stainless steel exhaust systems available. Originally specializing in Porsche 911 performance exhaust systems, oil coolers, and intercoolers, B&B introduced the Tri-Flo line named after its unique 3-into-1 Porsche header. Billy Boat continues to develop the highest performing exhaust systems for most sports cars, trucks, and SUVs.

Billy Boat exhaust systems start with T-304 stainless steel the highest quality material practical for after-cat exhaust applications. B&B exhaust tubing is mandrel bent on sophisticated CNC machinery for a precise fit and uninterrupted exhaust flow. B&B's use of T-304 stainless steel flanges offers high strength and complete resistance to harsh elements. All hangers, resonators, and tips are T-304 stainless steel as well.

Billy Boat Performance Exhaust mufflers have been developed in-house for years enabling them to give you the best possible product. B&B tunes each muffler to match its application for the best possible performance gain and sound quality combination. For strength B&B the muffler end-plates are radiused at the inlet and outlet preventing premature cracking. B&B auto parts uses reinforcing gussets when necessary.

Billy Boat Exhaust has spent the last ten years perfecting the sound of their exhaust systems. “We use two different packing materials and as many as three separate SCC’s inside the muffler”, says owner Billy Boat. This design creates the perfect harmony at any RPM range.

You want your exhaust system to look good as well as sound good. B&B auto parts are polished to a showroom finish and the exhaust systems are available with several different tip styles. Billy Boat Performance Exhaust offers a style and selection for everyone.

What’s the difference between our Billy Boat Exhaust Systems such as the C6 and C7?

BULLET Exhaust – Aggressive Sound

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 has quickly become the industry standard for a deep, aggressive muscle car sound on the C6. 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 your Corvette will scream ”muscle car”.

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

The Billy Boat Exhaust PRT 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 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.

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

Billy Boat Exhaust has designed a Fusion NO-DRONE exhaust for the factory NPP and the non-NPP option equipped cars such as the Corvette, Camaro, and CTS-V. On most cars with the Dual-Mode NPP option, the butterfly valve in the exhaust is controlled by the ECU. The valve opens based on RPM and throttle position. Our expertise here at BBE is getting the “tone” right for your car, and we think we nailed this one. Even in the closed position, the tone is deeper, louder, and more aggressive. Open the valves, the overall volume and tone increases to the point heads will turn when you drive up.

*Add our FCOR-0468 conversion 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.
