Another big chamber, hard hitting exhaust option for the Horizontal Minarelli engine from Athena. This pipe should only be paired with the large bore, high revving kits. Definitely not for stock cylinders or mild cast-iron kits.

From Athena themselves-
"The Athena R&D department has developed the new Athena steel Racing Complete Exhaust Kit with carbon muffler specific to legendary models like the APRILIA RALLY, MALAGUTI F10, F12, F15 and YAMAHA JOG.
This muffler is produced with precise craftsmanship and the most attention to detail to ensure proper expulsion of the gases produced during fuel combustion, preventing any fluctuations that would compromise the performance of the scooter.
The result? An exhaust that allows for greater torque and acceleration.
AESTHETICS AND DESIGN
The design is unique, as this JOG racing muffler is produced in high-quality 0.8 mm steel to ensure ultimate performance on any model of scooter. To respect the geometry, the muffler is made up of more than 18 sections that are hand-welded to each other, and includes a carbon silencer to ensure lightness as well as maximum resistance.
The fastening brackets are produced in AISI316 steel, durable, resistant and easy to clean. This steel is also stainless and does not rust."
