This guide will take a deep dive into the top exhaust systems for the Concours 14, covering performance, durability, sound, and value.
Why Upgrade Your Concours 14 Exhaust System?
Before we jump into our top picks, let’s understand why an upgraded exhaust system is a smart investment for Concours 14 owners.
Performance Boost
Stock exhausts are built with regulations and cost-efficiency in mind, often at the expense of performance. High-performance Concours 14 exhaust systems increase airflow, reduce backpressure, and significantly improve horsepower and torque.
Weight Reduction
Aftermarket exhausts, especially full systems or slip-ons made from titanium or carbon fiber, are substantially lighter than OEM systems. Shedding excess weight improves handling and fuel economy—key benefits for touring bikes like the Concours 14.
Aggressive Sound Profile
The right exhaust gives your Concours 14 the deep, throaty growl it deserves. Whether you prefer a subtle purr or a full-bodied roar, there’s a system that can match your sound preference.

It depends on your local laws and dealership policies. Slip-ons typically don’t affect the engine warranty, but full systems might, especially if ECU remapping is involved.
