B&B Cat Test Pipe Audi B7 A4 2.0T FSI 06-07
Each Billy Boat Performance Exhaust system incorporates 3 generations of fabrication skill and racing talent. Every system starts with T-304 stainless steel, known throughout the industry as the highest quality material practical for after-cat exhaust applications. All exhaust tubing is mandrel bent on sophisticated CNC machinery for a precise fit and uninterrupted exhaust flow. The use of T-304 stainless steel flanges also 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 are crafted in-house with years of racing and street development invested into the design. Each muffler is tuned to match its application for the best possible performance gain and sound quality combination. For strength, the muffler end-plates are radiused at the inlet and outlet preventing premature cracking. Additionally, reinforcing gussets are used when necessary. Depending on the application, you can choose from 3 inch round tips with a rolled edge, 4.5 inch oval rolled edge tips, 5.25 inch oval rolled edge tips or DTM style tips for European applications.
Billy Boat Test Pipes are the final step in maximizing flow from your exhaust system. Even a complete aftermarket exhaust system is greatly inhibited by a factory catalytic converter, yet many people overlook upgrading this part. Offering substantial horsepower gains in the higher-end of the power band, the Billy Boat Test-Pipes are made of Stainless Steel with a quality polished finish and bolt on directly, replacing the catalytic converter. Completely eliminating the catalytic converter is essential in high performance applications where every possible horsepower must be attained. The catalytic converter is the bottleneck of any high performance exhaust system. Eliminating this allows all of your other engine modifications to reach their full potential. A test pipe replaces the restrictive factory catalytic converter with a strait through pipe. Its strait through design will give your vehicle an aggressive race-inspired tone and is sure to turn heads. B&B test pipes are designed specifically with maximum performance in mind while maintaining quality finish and bolt on fitment. Contact Us with any questions.
