Invidia HS17CTRDPC 76mm High Flow Catted Downpipe

The Invidia HS17CTRDPC is a high-performance 76mm (3-inch) downpipe featuring a high-flow 200-cell catalytic converter designed to maximize exhaust flow and unlock significant power gains. Engineered to replace the highly restrictive factory downpipe, this upgrade optimizes turbocharger efficiency and improves overall engine performance.

Key Features:

• 76mm (3-inch) mandrel-bent stainless steel construction for maximum flow
• High-flow 200-cell catalytic converter maintains emissions compliance while reducing backpressure
• Precision laser-cut flanges ensure proper fitment and eliminate exhaust leaks

Constructed from high-grade SUS304 stainless steel, this downpipe delivers proven horsepower and torque gains throughout the powerband. The smooth mandrel bends eliminate turbulence and backpressure, while the high-flow catalytic converter provides an excellent balance between performance and emissions compliance.
