Description
REMARK x BOLD Quiet-Spec Cat-Back Exhaust for 2024+ Lexus GX550. Choose the GX550 Quiet-Spec cat-back for a more moderated sound-control layout.
Two muffler canisters distinguish this system: a main body fed by dual inlet pipes and a second straight-through canister near the rear. A single turndown tip keeps the rear presentation understated.
Outlet position is part of the installation choice, not just the appearance. Align the system with clearance around the body, spare tire, and nearby accessories before final tightening. A high-tuck layout can reduce exhaust exposure, but it does not replace checking suspension movement or compatibility with other underbody equipment.

Fitment and Installation
For the GX550 3.4L twin-turbo V6. This listing is the complete Quiet-Spec cat-back, not the rear-section conversion for an existing kit. The additional muffler targets sound suppression but does not establish a drone-free result for every vehicle setup.
