Hyosung GT250R AND GT250 Comet

The gt250r comet performance exhaust from Quill Performance Exhausts delivers exceptional quality, sound, and value for riders of the Hyosung GT250R and GT250 Comet manufactured from 2004 onwards. Designed and manufactured in the UK, this exhaust system provides a perfect blend of performance enhancement and deep, throaty exhaust note that transforms the riding experience of these popular quarter-litre motorcycles.

About the GT250R Comet Exhaust System

This premium aftermarket exhaust is engineered specifically for the Hyosung GT250R and GT250 Comet models, ensuring a perfect fit and optimised performance. The system features a straightforward 4-bolt fitting that attaches directly to your standard OEM downpipes, making installation remarkably simple for both experienced mechanics and home enthusiasts. Each exhaust comes complete with one stainless steel exhaust strap and one exhaust strap rubber, providing everything you need for a secure, vibration-free mounting.

The construction quality reflects Quill’s commitment to durability and performance. Built from high-grade stainless steel, this exhaust resists corrosion and maintains its appearance even after years of use in all weather conditions. The polished finish not only looks stunning but also requires minimal maintenance, allowing you to spend more time riding and less time cleaning.

Performance Benefits of the GT250R Comet Performance Exhaust

Upgrading to a Quill performance exhaust offers numerous advantages beyond the improved acoustic experience. The optimised internal design reduces back pressure compared to the restrictive standard exhaust, allowing the engine to breathe more freely. This improved gas flow typically results in modest power gains throughout the rev range, with noticeable improvements in throttle response and mid-range acceleration.

Weight reduction is another significant benefit. Aftermarket exhausts are typically lighter than stock systems, and removing unnecessary weight from the rear of the motorcycle improves handling characteristics and reduces unsprung mass. The gt250r comet exhaust maintains structural integrity whilst shedding excess kilograms, contributing to a more agile and responsive ride.

The enhanced exhaust note gives your Hyosung a more purposeful, sporty sound without being excessively loud or antisocial. The deep rumble adds character to the V-twin engine, making your riding experience more engaging whilst remaining considerate to neighbours and other road users. You can hear a demonstration of the exhaust note in action through the YouTube video showcasing the system.

Installation and Fitment for the GT250R Comet

One of the standout features of this exhaust system is the ease of installation. The 4-bolt mounting system connects directly to your existing standard downpipes, eliminating the need for cutting, welding, or purchasing additional components. The included stainless exhaust strap and rubber ensure a secure, rattle-free fit that maintains alignment even under hard acceleration and spirited riding.

Most riders with basic mechanical skills and a standard toolset can complete the installation in under an hour. The process typically involves removing the old exhaust, positioning the new Quill system, securing the mounting bolts, and adjusting the exhaust strap for optimal positioning. Always ensure all fixings are properly torqued to manufacturer specifications to prevent loosening during use.
