Nissan GT-R R35 3.8TT Downpipe Exhaust System (2008-2024)

Maximize Turbo Spool & High-Flow Velocity — CEES Nissan GT-R R35 3.8TT Downpipe Exhaust System (2008–2024)

Unleash the true power and twin-turbo responsiveness of your Nissan GT-R R35 3.8TT V6 (VR38DETT / 2008–2024) with the CEES High-Flow Downpipe Exhaust System. Precision-engineered from heavy-duty T304 stainless steel, this system removes the severe backpressure restrictions of the factory catalytic converters right off the turbo turbine outlets. Expect dramatically quicker boost spool, enhanced throttle sensitivity, and an aggressive, authoritative VR38 exhaust note under acceleration.

🚀 Engineering Highlights

• Optimized Turbocharger Gas Velocity: Smooth mandrel-bent oversized stainless piping eliminates extreme exhaust bottlenecks directly at the turbo turbine exits, drastically reducing backpressure and accelerating boost response.
• High-Flow Catted & Catless Configurations: Available in full Catless (Track/Motorsport use) with or without integrated high-temp thermal heat shielding, as well as High-Flow Metallic Catted (100 / 200 / 300 cell density) for balanced flow and daily usability.
• Integrated Thermal Heat Shielding Option: Optional multi-layer stainless heat insulation effectively contains radiant turbo heat inside the downpipes, significantly reducing underhood engine bay temperatures.
• Master-Tier Hand TIG Welding: Constructed with precision fixtures and uniform high-density TIG welding for smooth internal airflow transitions and long-lasting structural durability under intense track heat.
• 3D Scan Direct Bolt-On Precision: Developed from 3D laser underbody scans to ensure direct alignment with factory turbocharger outlets, OEM bracket locations, and downstream Y-pipe exhaust connections.

FAQ

1. What is the difference between Catless and High-Flow Catted downpipes?

The Catless version completely removes internal catalytic restriction for maximum exhaust gas velocity, fastest turbo spool, and aggressive motorsport acoustics. The High-Flow Catted options (100, 200, or 300 cell) use durable high-flow metallic substrate catalytic converters to significantly reduce backpressure over factory units while minimizing raw exhaust smell.

2. What are the benefits of the heat shield option?

The integrated multi-layer thermal heat shield locks high exhaust heat inside the downpipes, preventing heat soak into surrounding engine bay components, wiring, and brake fluid lines, ensuring lower intake air temperatures during spirited or track driving.

3. Will installing downpipes trigger a Check Engine Light (CEL)?

Altering catalytic converter flow can affect secondary oxygen sensor readings. To help ensure trouble-free operation, orders include complimentary O2 sensor CEL fix spacers. For optimal engine performance, boost control, and fuel calibration, an ECU tune (Stage 2) is recommended.

4. Is this exhaust direct bolt-on?

Yes. The exhaust features 100% bolt-on installation allows a return to stock at any time. (Reuses factory outlets). It bolts directly to the factory VR38 turbo turbine discharge flanges and connects smoothly to either the OEM Y-pipe or CEES high-flow Y-pipe.
