FAQ'S
1. IS THERE A DIFFERENCE IN PERFORMANCE BETWEEN DUALS AND SINGLE EXHAUST SYSTEMS?
The performance gains are the same for duals and single systems. The duals offer a deeper more aggressive sound over the single system. This is due to the extra tail pipe and the fact that most dual systems have a slightly different muffler configuration than the single systems.
2. WHAT DOES "OFF - ROAD" MEAN?
An "Off-road" system is designed to deliver all out power gains. These systems make no provisions to retain the factory catalytic converter. Some jurisdictions do not allow the removal of your vehicle's catalytic converter therefore they can only be legally used off of the highways.

12. WHAT STYLE OF MUFFLER IS USED?
The muffler used on all of MRBP diesel systems is a straight flow through design with a spiral louver core. The muffler is packed with stainless steel wool which is then wrapped with a ceramic fiber blanket. This combination creates the deep mellow exhaust note that MBRPinc. systems are known for. MRBP Performance Gas systems use a variety of high flow muffler designs utilizing the same spiral louver core design as MRBP diesel mufflers or tuned chamber designs specific to the application intended.
