SPDZ1 Muffler Delete Axle-Back Quad Tip Exhaust – 2021+ Lexus IS300 / IS350

Transform the sound and presence of your Lexus IS with the SPDZ1 Muffler Delete Axle-Back Quad Tip Exhaust, engineered for drivers who want a more aggressive tone and a sportier rear profile without compromising fitment or quality.

This axle-back system replaces the restrictive factory mufflers with free-flowing mandrel-bent stainless piping, unlocking a deeper, louder exhaust note and sharper throttle response. Designed as a true bolt-on upgrade, the SPDZ1 system installs cleanly using factory mounting points for an OEM-style fit with a performance edge.

Finished with quad double-wall slant-cut tips, this exhaust not only sounds aggressive but visually elevates the rear of the IS300 / IS350 with a clean, high-end appearance worthy of the Lexus badge.
