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

A: Please check your respective state and local regulations to confirm noise and emission compliance. Surprisingly, Blow Performance Exhausts are not much louder even with the baffles removed, the unique 3-step design keeps the volume down and gives it a deep gutsy sound. DB readings are approx. 108db @ 2500 rpm, taken from a 96ci Harley Davidson stock Fatboy.

For customers based in the USA, please read our Disclaimer and Emissions Notice


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

A: No, you don't need a professional mechanic, however if you're not familiar with mechanical work we suggest you seek professional assistance. The exhaust comes with everything needed to bolt on however, does not come with exhaust mounting brackets, flange and retaining ring kit and flange nuts. Simply use your existing ones or purchase new. Comes with 18mm Oxygen Sensor Bungs and 12mm reducers as well as blanking caps for carburetor models. You need to tune the engine after installing the exhaust system. Our exhaust system requires you to fit a sports performance air cleaner to allow the system to reach maximum performance levels. The system is designed to run without the baffles and leaving them in will reduce HP and mid-range torque.
