Show original supplier description
The Spark GKT0110 is a double exhaust system meticulously engineered for the KTM Duke 790 models from 2018 to 2020. This system features two GRID-O silencers, each measuring 215mm in length, designed for a high-mounting, underseat configuration on both the left and right sides. It connects seamlessly to the original catalyzed collector using stainless steel pipes. Crafted with advanced technology and materials, the Grid-O silencers are a product of Spark R&D's extensive work on WSBK and Moto2 race tracks. Available options include titanium silencers with either approved (GKT0110TOM) or non-approved (GKT0110T) materials. The system weighs approximately 3.0 kg, a reduction from the stock weight of 3.3 kg. It is EURO 4 compliant and offers homologation for street use. The sound is described as gloomy and aggressive, made possible by a removable dB killer, while still adhering to regulatory dB limits. The Grid-O slip-on aims to increase performance by approximately 2 hp compared to the standard exhaust.
