BUN Freestyle has changed the game with their exhaust chambers that work on a Yamaha based platform (I.E. Dasa, TPE, ET, XScream). This is the same design used for their own manufactured engines - the WAZ engines. 

The aluminum chamber is half DRY and half WET. Meaning the front half of the chamber is water jacketed with NO water in the inner chamber, and the back half of the chamber then has water injected inside. This works EXTREMELY well for mid to top power, with plenty of power still being made on the bottom end. 

This aluminum chamber is also the LIGHTEST aluminum lay down exhaust in the industry. Pairs with the PFP exhaust manifold. 

For BEST PERFORMANCE - we recommend pairing the BUN water box with the chamber as they are made to work in harmony. The chamber will still work without the water box, but you will not have as great of results.

*Fittings not included - You will need the special 1/2" to 1/4" tee fitting for the aluminum chamber (this can be added below)

*The BUN Yamaha edition exhaust chambers are meant to be used with a PFP exhaust manifold

PLEASE NOTE - The WAZ edition and Yamaha edition chambers are NOT interchangeable. They do used different sized ends. Please order accordingly.

If the item is not in stock, we will have it soon.
