B&B Billy Boat Exhaust FPIM-0503 - Billy Boat B&B Audi A4 - B7 A4 Quattro 2.0T Manual; 2005-2008.

Billy Boat Performance Exhaust’s A4 exhaust from LMPerformance 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.
