ELECTRONICALLY AND MANUALLY ADJUSTABLE SOUND SYSTEMS

All KESSTECH accessory exhaust systems impress because of their unmistakable, unique and completely legal sound as well as because of the design that is influenced by the characteristics of the machine/vehicle. We differentiate here between electronic soundmanagement systems (ESM2/ESM1) and manual mechanically adjustable sound systems (MMV). 

We offer the respective systems as complete systems or as slipons – depending on the vehicle type in different sizes (size of the rear muffler, one or two exhaust pipes) and colour impressions (chrome-plated, matte black powdered). In most cases, these can be customised still further by a large selection of end tips.

These mufflers can be the answer for EPA sensitive markets that want to not only follow the letter of the law for ARB restraints, but also for noise compliance.  A little expensive, but an option.  Check www.kesstech.de for more information.
