ARROW Indy Race full exhaust system, homologated, in black aluminum with stainless steel headers for YAMAHA YZF R9 25-26

ARROW Indy Race 71981AKN full system in black aluminum with stainless steel collectors for YAMAHA YZF R9 25-26

This is the INDY RACE EVO system with a carbon end cap, which is the black aluminum model with a stainless steel mid-pipe and stainless steel collectors.

The 71981AKN exhaust is based on one of ARROW's historical product lines, which has been renewed to become an even more absolute icon among versatile exhausts that adapt well to all types of motorcycles.

The shape, which recalls the ovals of the Indy formula from which it derives its name, is enriched with technical details such as the new side embossing that not only gives the exhaust a very pleasing appearance but also makes it even more robust and rigid.

The design of the Arrow Indy Race Evo exhaust is inspired by Indy racing and has been carefully optimized to maximize exhaust flow and increase engine power. Each curve and detail has been meticulously adjusted to ensure a fluid and unrestricted gas output, resulting in impressive sound and response.

What material is it made of?

The silencer body is made of aluminum, which allows the exhaust to be much lighter compared to steel. This material also dissipates heat more effectively, which contributes to improved performance. Aluminum is highly corrosion-resistant and has a glossy appearance. Additionally, the exhaust features a black finish, which is achieved through a ceramic-based painting process, resulting in a more aggressive look.

The collector is made of high-quality austenitic stainless steel, which offers high corrosion resistance, improved high-temperature resistance properties, and perfected formability.

The durability of the materials used for its development are circuit-tested to ensure optimal performance on the road.
