Upgrade your Infiniti Q50 or Q60 3.0T VR30 exhaust system with these high‑flow Catless Lower Downpipes engineered for performance gains and improved exhaust flow. Designed as a direct OEM replacement for the restrictive factory secondary catalytic converters, this non‑resonated downpipe kit increases turbo efficiency, reduces backpressure, and enhances throttle response.
Built from durable stainless steel with precision TIG welds and flanges for a secure fit, this kit is tailored for enthusiast drivers looking to extract more power and torque from their VR30 engine.
Key Features
- Precision TIG‑welded stainless steel construction for strength and longevity.
- Direct bolt‑on fitment: replaces the OEM lower catalytic converter section without cutting or modification.
- Improved exhaust flow compared to stock, helping turbo spool faster and reducing restrictions.
- Designed to increase torque and horsepower potential when paired with supporting mods and tuning.
- Non‑resonated design for a sportier exhaust sound without excessive drone.
- Includes all necessary hardware for installation.
Benefits
- Enhanced Performance: Eliminates the restrictive secondary catalytic converter, helping improve exhaust velocity and turbo efficiency across the powerband.
- Faster Turbo Spool: Reduced backpressure promotes quicker boost response and stronger mid‑range torque.
- Aggressive Exhaust Tone: Non‑resonated design delivers a more spirited sound under throttle without becoming unpleasant at cruising speeds.
- Durable & Long‑Lasting: Stainless steel materials resist corrosion and maintain appearance under high‑heat operation.
