OTT Catted Downpipe - 2024+ Tacoma/4Runner/LC250 Pre-Order

[JustDSM]

T24A-FTS Toyota Tacoma/4Runner/LC250 Catted Stainless Steel Downpipe

This 4″ full mandrel-bent downpipe is engineered to deliver exceptional performance and long-term durability. Its optimized design promotes faster turbo spool and earlier power delivery by allowing exhaust gases to flow efficiently. Smooth, gradual transitions throughout the mandrel-bent sections help maintain exhaust velocity while minimizing backpressure within the system.

Product Details:

• Direct fit for all 2.4L turbo Tacoma, 4Runner, and Land Cruiser LC250 platforms, including both hybrid and gasoline models
• Complete bolt-on solution for OEM Turbo configuration
• CAD-designed and mandrel-bent to maximize exhaust flow while ensuring precise fitment and high-quality finish
• Configurable for the factory ball/socket flange (standard configuration) or compatible with aftermarket exhaust systems (optional)
• Constructed with a CNC-machined 304 stainless steel turbine outlet, 3″ flex section, and 3″ exhaust outlet (when configured w/ aftermarket flange)
• Turbine flange is designed to provide a smooth, uninterrupted transition from the turbo outlet
• O₂ sensor bungs located in factory positions—no sensor extensions required
• Eliminates check engine lights through use of an EPA-approved GESI Gen2 catalyst (not available for sale in California)
• Handmade in the USA
