Upgrade the exhaust system on your legendary Toyota 3S-GTE turbo platform with this high-performance 3-inch stainless steel turbo downpipe and dump pipe assembly.

Designed for the Toyota Celica GT-Four, Celica All-Trac and SW20 MR2 Turbo, this high-flow downpipe is engineered to improve exhaust evacuation directly from the turbocharger. The freer-flowing design helps reduce turbine outlet restriction, improve turbo response and support increased horsepower on street, rally, drag, track and high-boost performance builds.

Constructed from polished stainless steel with a heavy-duty 3/8-inch-thick turbo flange and approximately 2.7mm-thick tubing, this downpipe is built to withstand the extreme heat, vibration and pressure produced by modified 3S-GTE engines.

The system features a CT20 / CT26-style turbo flange, a 3-inch flanged outlet, reinforced support welds, mandrel-bent piping and an additional race bung. The design also allows the alternator air cooler duct to be refitted and retains compatibility with the factory wastegate configuration.

• Helps reduce restrictive factory exhaust backpressure
• Supports faster turbo spool and improved turbocharger response
• Improves exhaust flow directly after the turbine outlet
• Supports increased horsepower and torque on properly tuned vehicles
• May help lower exhaust gas temperatures under high-load operation
• Improves high-RPM exhaust efficiency
• Ideal for upgraded exhaust systems and modified 3S-GTE engines
• Suitable for street performance, rally, drag, autocross and track builds

Important: Toyota used different turbocharger, catalytic converter, oxygen-sensor and exhaust configurations across markets and model years. Compare your original flange locations, outlet position and sensor arrangement with the product photographs before ordering.

Only the components specifically shown in the product photographs and listed above are included.

Professional installation is strongly recommended. Installation requirements may vary depending on the vehicle model, engine generation, turbocharger, existing exhaust system and previous modifications.

Test-fit all components before final tightening. Verify clearance around the oil pan, alternator, driveshafts, cooling components, wiring, oxygen sensors and surrounding heat-sensitive parts.

Product appearance, weld placement, sensor bung location and included hardware may vary slightly as manufacturing improvements are introduced.
