5: DO I NEED A PROFESSIONAL MECHANIC TO INSTALL THE EXHAUST SYSTEM? DOES THE KIT COME READY TO INSTALL?
A: Yes, everything you need is in the Exhaust system kit. We recommend they be fitted by a reputable motorcycle service centre; the bike will require tuning once the exhaust is fitted, within a few months, we strongly recommend having the bike DYNO TUNES by a professional.

If you have a strong knowledge of motor mechanics you will find it extremely simple and quick to install, we provide a 10-minute Installation Video. For more Information and installation video Please read our “INSTALLS” section in this website.

CUSTOM & CHOPPER - Please contact us. We recommend a performance air-cleaner, with some models check your standard air-cleaner will not interfere with the exhaust fitment and installation.

8: DO BLOW PERFORMANCE EXHAUSTS INCREASE PERFORMANCE?
A: Yes, Blow Performance Exhaust Systems are 3-Step Headers and not to be confused with straight through drag pipes. Installed correctly, with a sports air cleaner & professionally Dyno Tune, our 3- step header system will increase power & torque by dramatically increasing the scavenging effect with your engines. Please read our “ABOUT” section in this website.

9: WILL I LOSE POWER OR TORQUE, WHAT ABOUT BACK-PRESSUE?
A: No, you will increase power and torque with our 3 step headers. Please read our “ABOUT” section (bottom of the page) in this website.

10: WILL I GET POPPING OR BACK-FIRES?
A: Popping is caused by reversion, usually when you have installed a very big cam that has a wide overlap with the intake and exhaust opening. Correct Dyno Tuning also helps. Our systems are 3- step headers which reduce reversion.

11: WILL THE CHROME DISCOLOR?
A: Discolouring or blueing occurs when the engine is running too lean, this causes the engine to run very hot. Our systems are Internally Coated with Heat Resistant Materials to help prevent overheating. The following will prevent discolouring:
1. A professional Dyno Tune
2. Not revving or idling the bike for long periods of time in a stationary or non-ventilated area.

12: DO YOU PROVIDE MAP SETTING?
A: No two engines are the same, and for this reason we do not provide map setting. To achieve the optimum performance level, have the bike Dyno Tuned by a professional.

13: ARE THE STANDARD & PRO PERFORMANCE EXHAUST BAFFLES EASY TO INSTALL OR REMOVE?
A: Yes. Under 5 minutes! You will need to retune your engine each time you install or remove baffles. Most customers do not purchase baffles. For more information on our baffles please read out “PARTS” section in this website.

14: ARE THE EXHAUST LOUD?
A: Not as loud as you may expect, they are not drag pipes, our systems have a deep amazing sound. For more information on DB LEVELS & HP PERFORMANCE please read out “PARTS” – BAFFLES section in this website. Also visit our Facebook, Instagram & YouTube for Video and sound.
