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 carbon chambers are a full WET chamber. Meaning there is only one cavity inside the chamber with water injection. This chamber utilizes 2 injection points. This chamber still has the unique shape of the BUN aluminum chamber, but offers more bottom end punch with being fully wet.
This carbon chamber is also the LIGHTEST lay down exhaust of any kind in the industry. Weighing in at 2.2 lbs (1 Kilo) and made with prepreg dry carbon - you can't beat it! 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.
