Overview

It features a larger diameter than standard OEM parts to allow more gas to exit the engine, increasing efficiency. When used with a Catalyst Bypass Pipe, this downpipe can provide significant power gains without restricting gas flow.
Show original supplier description
Fabricated with a larger diameter than standard OEM parts, this downpipe allows for significantly increased gas flow from the engine, thereby boosting overall efficiency and power output. When paired with a Catalyst Bypass Pipe, it offers substantial power gains by eliminating restrictions imposed by a catalytic converter. This downpipe is constructed from premium Type-T304L aircraft-grade stainless steel, known for its anti-magnetic properties and resistance to discoloration. The system utilizes mandrel-bent tubing to ensure smooth, unrestricted bends for optimal gas flow, and the bore is increased to maximize performance without sacrificing mid-range torque. All Milltek Sport performance exhaust systems are designed, developed, and manufactured in the UK. Crucially, it requires a Stage 2 ECU Remap to function correctly. The pipe diameter measures 76.2mm (3 inches) and it is not EC approved.
