Exhaust Yasuni 4 Black Carbon Honda PCX 125cc

4-Stroke Exhaust Yasuni 4

Yasuni got into the maxi scooter market, and their exhaust systems are convincing as ever. The Yasuni 4 is an excellent exhaust system for 4-stroke maxi scooters, and it is street-legal.

The Yasuni 4 is the perfect combination of impressive performance, classy design and ear-pleasing sound. Scooter owners who are looking for a high-end replacement for their stock exhaust can expect a 10% increase in power, and torque is improved as well. It is really easy to mount and features several advantages over the original exhaust. It weighs ca. 40% - 50% less than the stock pipe which leads to improved agility.

The stainless steel head pipe does not consist of a single piece as is the case with most other 4-stroke systems - Yasuni goes all out and beyond, the manifold is the only one available (to date) that is welded from several cones. It has a progressive diameter to optimize performance. It generates negative pressure in the header pipe to reduces the base pressure and thus optimizes the gas flow. The aluminium silencer has a black finish with a carbon end cap and Yasuni logo.

Assembly is quick and easy, small parts such as clamps, silentblocs, springs and screws are included.

A matching catalytic converter is available separately.

• Header pipe made from stainless steel AISI-304
• Colour: Black Edition / Carbon end cap
• With ECE homologation / road-legal
