HSI assembled Yamaha BUN Freestyle carbon exhaust kit.
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.
This complete kit includes all components that are needed to install this exhaust on your 701+cc Yamaha based engine with you already owning the exhaust manifold. Instructions included.
PLEASE NOTE - This kit does NOT include the Power Factor exhaust manifold, exhaust manifold gasket, or exhaust manifold fittings. Here you can find the COMPLETE SYSTEM.
