Milltek Large-bore Downpipe and Hi-Flow Sports Cat (200 Cell) M340i - SSXTY168
 
Every Milltek system is designed, developed and hand-finished here in the UK by time-served craftsmen, each one produced in aerospace grade type 304, non-magnetic stainless steel. This superior material is less susceptible to discolouration, lasts almost indefinitely and is used throughout the entire construction of our pipework, silencers and associated hardware.

Mandrel bending ensures constant radius bends for optimised gasflow, and bore diameters are carefully enlarged over stock to ensure ultimate performance without the loss of mid-range torque. All of the Milltek exhaust systems endure a comprehensive acoustic development process to deliver a tone that is sporty and crisp, without ever inducing NVH, drone or cabin resonance.
 
Enhanced Performance: Features a 200 CPSI (Cell) internal substrate construction, which boosts exhaust gas flow and cuts back pressure.
Speedier Turbo Spool: Increases spool times in turbo-powered engines for quicker acceleration.
Ideal for Tracks: This downpipe is specially designed for track applications, where each second can make or break a race.
Improved Acoustics: The high-flow race cat delivers a sportier and louder exhaust tone.
Robust Construction: Built with high-quality materials, this downpipe offers durability alongside performance.
Quality Assured: Designed and manufactured in the UK with a Milltek Lifetime Warranty*, giving you additional peace of mind and total confidence in your purchase.
