The Lexus GX 550 carries real presence on the road, and its 3.4 twin-turbo V6 has the depth to match it. This Milltek resonated cat-back runs mandrel-bent T304L stainless at 2.5in (63.5mm) bore, with a resonated centre section that gives the V6 a deeper, fuller tone while keeping the refinement that makes the platform so good. A high clearance outlet in place of tips, keeping the exhaust tucked higher under the vehicle for approach and departure angles on a lifted or off-road build. Direct fit to the OE hangers, no cutting required. Engineered for the Emotion.

Description

Milltek Resonated Cat-Back Exhaust for the Lexus GX 550 3.4 Twin-Turbo V6

The GX 550 sits a step above the trucks it shares a price bracket with, and this system is engineered to match. A full T304L stainless cat-back replacement built to give the twin-turbo V6 a deeper, fuller voice without costing the platform its character or refinement. The high clearance outlet keeps the exhaust tucked higher under the vehicle, so ground clearance is not the price of a better exhaust note.
