1Q: ARE BLOW EXHAUST SYSTEMS LEGAL AND ARE THEY LOUDER THAN OTHER AFTER MARKET PERFORMANCE EXHAUSTS SYSTEMS?

A: Blow Performance Exhausts are designed for closed circuit use and not for street. In most territories without the Standard Exhaust Baffles or Pro Performance Baffles they would not meet EPA regulatory Levels however, Blow Performance Exhausts Systems are shipped worldwide and not all countries restrict race production equipment for street use.

Please check your respective EPA Regulatory Authorities for compliance levels.
