The factory stock X5
features the powerful V-8 and produces alot of HP and
TQ. 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.
mandrel bent, T-304 stainless
steel and precision hand-craftsmanship, the
system for the 545i 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
545i. With a fully-polished
muffler and twin
3.5" fully-polished double-wall tips the
Billy Boat system delivers well beyond expectations.
