Description Khrome Werks 202712P Louvered Insert for 4.5” Slip-Ons The Khrome Werks 202712P louvered insert is designed to fine-tune exhaust performance on Harley-Davidson® touring models. Specifically, it fits 4.5” Khrome Werks slip-on mufflers from 2017 and newer. By improving airflow, this insert increases low-end torque and throttle response. At the same time, it refines the exhaust tone for a deeper, more controlled sound. As a result, riders get stronger pull without excessive noise or harshness. In addition, the louvered design helps maintain proper back pressure. Because of this, performance stays balanced across the powerband. Moreover, the insert installs easily with no permanent modifications required. Key benefits include: Improved low-end torque and throttle response More refined exhaust tone with a deeper sound Designed for 4.5” Khrome Werks slip-on mufflers Compatible with 2017-newer Harley-Davidson® touring models Easy installation with no cutting or welding Khrome Werks 202712P louvered insert is an ideal upgrade for riders who want better performance without replacing their entire exhaust system.
