Maximize performance and unlock the full potential of your twin-turbo V6 with the Untd. Performance 3″ Lower Catless Downpipe for the Infiniti Q50 and Q60 VR30 3.0T. Designed to complement upper downpipe upgrades or work as a standalone performance mod, this lower section features a full 3-inch catless design that eliminates remaining factory exhaust restrictions—boosting flow, throttle response, and exhaust tone for a sharper, more aggressive driving experience.

Key Features:

Full 3-Inch Catless Design
The Untd. lower downpipe replaces the restrictive lower factory catalytic converters with a straight-through, high-flow 3” pipe, dramatically improving exhaust gas evacuation and reducing backpressure. Ideal for turbocharged engines, this design supports faster spool and significant power gains, especially when tuned.

Optimized for Flow and Power
Whether used with factory upper downpipes or paired with a full catless system, this lower downpipe helps the VR30 breathe more freely—delivering noticeable gains in low-end torque, mid-range punch, and top-end power. It’s the perfect supporting mod for stage 2+ builds or those seeking maximum performance without compromise.

Aggressive Exhaust Note Enhancement
Removing the secondary catalytic converters allows for a louder, deeper, and more pronounced exhaust tone. Combined with upgraded upper downpipes or exhaust systems, this mod unleashes the true sound of the VR30—bold, responsive, and unmistakably performance-driven.

304 Stainless Steel Construction
Constructed from high-quality 304 stainless steel, this downpipe offers excellent corrosion resistance, high heat tolerance, and long-term durability. Precision TIG welds and CNC-machined flanges ensure proper fitment and leak-free performance, making installation smooth and reliable.

Track-Focused Design
Built with serious performance in mind, this component is ideal for off-road or motorsport use where emissions compliance isn’t required. Whether you’re optimizing for dyno pulls, competitive events, or weekend canyon runs, this downpipe supports high-output applications with ease.

Compatibility:

Infiniti Q50 3.0T VR30 Twin-Turbo V6
Infiniti Q60 3.0T VR30 Twin-Turbo V6

Whether used on its own or as part of a full turbo-back system, the Untd. Performance 3″ Lower Catless Downpipe is a must-have upgrade for enthusiasts looking to push the limits of their Infiniti’s VR30 platform. From sharper response to a more exhilarating exhaust tone, this downpipe delivers race-proven results.
