Frequently Asked Questions

(Please email us for further information should you require at enquiries@blowexhausts.com)

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 Baffles or Catalytic Converters 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.

Blow Performance Exhausts are not much louder even with the baffles removed, our 3-step Headers are designed for low sub frequencies which gives them their deep gutsy sound and not an ear piercing high pitch sometimes heard with straight through pipes. An example reading taken from a 96ci Harley Davidson stock Fat Boy was approx. 108db @ 2500 rpm This is comparative to similar quality aftermarket Exhausts

2Q: DO I NEED A PROFESSIONAL MECHANIC TO INSTALL THE EXHAUST SYSTEM? DOES THE KIT COME READY TO INSTALL?

A: We recommend they be fitted by a reputable motorcycle service centre, the bike will require tuning once the exhaust are fitted.
