Milltek High Clearance Resonated Cat-Back exhaust - Lexus GX550 3.4 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.
