VCTR Performance BMW M3/M4 F8X S55 Downpipe Kit

Overview

This high-flow catted downpipe replaces the factory OPF section on the F8X S55 with a less restrictive catalyst. Retains catalytic function for road-registered S55 applications, with a heat shield included for underbonnet protection.

Why Upgrade?

• High-flow catalyst significantly less restrictive than the factory pre-cat or OPF
• Improved exhaust flow and turbo response versus the OEM downpipe
• Retains catalytic converter — better suited to road-registered vehicles
• Stainless steel construction for durability
• More defined exhaust tone on tuned applications

Engineering Focus

SS304 stainless steel with high-flow OPF replacement catalyst and heat shield. Designed for road-use S55 builds where a catless unit is not appropriate.
