The stock 535i features the powerful Twin Turbo Inline 6 engine and produces 300 HP and 300lb-ft. of torque. Developing an exhaust system worthy of this outstanding automobile was a tall order. Billy Boat Performance Exhaust was up to the task and delivered the ultimate performance exhaust for this beautiful BMW.
Featuring mandrel bent, T-304 stainless steel and precision hand-craftsmanship, the system for the 535i provides custom-tuned performance with a harmonious, subdued exhaust note and no interior resonance. The proprietary design of each Billy Boat Performance Exhaust provides increases in horsepower and torque throughout the entire RPM band.
Aesthetics were another important factor in the development and design of this muffler system. Simply providing performance gains and a balanced exhaust note were not enough to declare this the ultimate system for the expertly engineered BMW 535i. With a fully-polished muffler and twin 3.5" fully-polished double-wall tips the Billy Boat system delivers well beyond expectations.
