HSI assembled COMPLETE Yamaha 61x BUN Freestyle carbon exhaust system.
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.
The complete kit includes all components that are needed to install this exhaust system on your 701+cc Yamaha based engine. Instructions included.
If the item is not in stock, we will have it soon.
** A charge for shipping / importing from Japan is already added to the listed price.
