The Remark midpipe kit for 2014–2020 Lexus IS350 V6 replaces the factory midsection and includes a high-flow catalytic converter plus resonators to manage sound and flow. Intended as a direct replacement midpipe, it supports freer exhaust flow while retaining emissions control via the supplied cat. Use this kit when upgrading downstream exhaust components or restoring midpipe functionality.
