The Benefits of the new PRT Sport Exhaust for the BMW E60 535TT

Billy Boat Performance Exhaust line of performance exhaust for the BMW E60 535TT incorporates the latest in resonance control technology, B&B’s proprietary Purge Resonance Technology or PRT as it is known. Completely reengineered the PRT system allows you to have a mild exhaust note at cruising speeds yet a forceful note on aggressive driving. The complex yet simple design gives you the increased sound and performance you are looking for with its straight through design on moderate to hard acceleration and then the unique purge chambers cancel out the unwanted interior noise during low rpm cruising speeds.

3.5" Exhaust

The development team here at Billy Boat Performance Exhaust did extensive testing on the muffler exhaust system for the BMW E60 535TT , looking at the both the 3.0" exhaust and the 3.5" exhaust. We found the best performance and best turbo spool-up to be with the 3.5 muffler system, which is slightly larger than the factory system. This allows us maintain the low restriction muffler for quick acceleration, while gradually increasing the exhaust velocity throughout the system for greater horsepower and torque. These results have been confirmed by the chassis dyno and by our customers. The use of our PRT muffler design keeps the tone aggressive yet unobtrusive.
