B&B Billy Boat Exhaust Billy Boat B&B Audi A4 - B7 A4 Quattro 2.0T Tiptronic FPIM-0504

Billy Boat Performance Exhaust’s A4 exhaust is precision crafted using 100% T304 stainless steel. Starting right after the catalytic converter the B&B system has a 2.5” downpipe that leads into a center muffler. Upon exit of the center muffler the system splits into two 2.25” pipes that direct the exhaust to a pair of rear mufflers that incorporate B&B’s proprietary Purge Resonance Technology (PRT) which is the latest in resonance control technology. The straight through design mufflers emit a deep sporty note on hard acceleration while the purge chambers collect and cancel the unwanted resonance at cruising speeds giving the car a nice mild touring tone with no interior resonance. Another benefit of the straight through PRT design mufflers and the CNC mandrel bent tubing is an increase in both horsepower and torque. Bold yet stylish 3.5” round double wall tips finish off the system for a distinctive look. Features: 3 1/2 Twin 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.

* Black Tip Option will add aprox 1 week to ship time.

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.
