Product Description

The aFe POWER Vulcan Series 2-1/2 IN to 3 IN 304 Stainless Steel Cat-Back Hi-Tuck Exhaust System (PN 49-36085) is purpose-built for the 2024-2026 Lexus GX550, delivering serious off-road performance without sacrificing the refinement GX owners expect. The system replaces the restrictive factory exhaust with mandrel-bent 304 stainless steel tubing, flowing exhaust gases more freely to help unleash the full potential of the GX550's 3.4L twin-turbocharged V6. The high-flow stainless steel muffler produces a commanding sound that complements the GX550's performance character - noticeable and aggressive without being excessive.

What sets this system apart for off-road applications is the Hi-Tuck tip design, engineered specifically to tuck the exhaust outlet higher and tighter to the vehicle. This maximizes approach and departure angles during technical trail driving, protecting the exhaust system from rock strikes and debris on steep descents or obstacle crossings. Whether you're running the stock Overtrail/Overtrail+ suspension with its 33-inch all-terrain tires, or you've added a lift to a Premium or Luxury trim, this exhaust is designed to clear without compromise. Every component is 100% MIG-welded and finished to aFe POWER's exacting standards at their Corona, California manufacturing facility.

Installation is a direct bolt-on process using factory-style flanges and OE-style hangers, meaning there is no cutting, drilling, or custom fabrication required. The system mounts to all existing factory mounting locations for a secure, rattle-free fit that installs with basic hand tools in a single afternoon. This exhaust fits all six GX550 trim levels - Premium, Premium+, Luxury, Luxury+, Overtrail, and Overtrail+ - as all share the same 3.4L twin-turbo V6 and full-time 4WD drivetrain configuration. If you're building out the GX550 for serious off-road use, weekend overland trips, or simply want to improve exhaust flow and sound on your daily driver, the aFe Vulcan Series is an ideal starting point.
