HammerHead High-Performance Exhaust Kit with Intake, UNI Filter and Jets for 150cc, GY6

Product Review (submitted on April 30, 2018):

I installed this kit on a single seat 2003 Dazon 150cc, and helped make the buggy very quick. The tone is great the performance is fantastic.
Here's a video of that Dazon racing what was commonly known as one of the fastest 150's around (that's a 180cc Blade with a 4 valve head being beaten by a Dazon with this exhaust, an adjustable CDI, and some drive train work).
