GY6 Air Performance Upgrade - Level 3

** Hammerhead Performance is currently out of stock on the exhasut for this kit **

This is our top performance exhaust kit!

Why is this a great product?

Increasing the amount of air and fuel that your engine can process results in increased horsepower. This exhaust package disposes of your restrictive stock air filter box for a free-flowing UNI pod air filter with a velocity stack cold air intake setup, and combines that with a high performance exhaust and larger diameter header pipe tuned for 150cc buggies.

The result? More horsepower on tap at all speeds.

This package truly delivers a significant performance jump over the stock setup. You'll definitely notice the "seat of the pants" difference in power.

All of our customers who have purchased and installed this kit have been VERY happy with the performance!

Tuning tips:

You will need to rejet your carburetor when installing this mod. Click here to learn how. You may need to purchase addition main and pilot jets for use with this system.

If you run at or above 5,000', start with a 130 main jet and your stock pilot jet. Around the 3,000' level we recommend a 135 main jet and 38 pilot jet, and at sea level --> 1,000' we recommend using a 140 main jet and 40 pilot jet.

Your system may vary slightly depending on your buggy and elevation, so it's good to get one size main jet above and below the recommended size above, along with a couple of regular NGK spark plugs for testing.

This exhaust has been installed and works on most models of 150cc based buggies from many manufacturers. Some slight modification to the header pipe bends may be required depending on your buggy.

If your buggy is not listed below, it does not mean that it will not install, just that we have not tested it directly on that model.
