PSR 9Line was built on a simple principle: source the right parts, from the right manufacturers, and make them accessible to Porsche owners who care about quality. Today, that principle takes a significant step forward. We're delighted to announce the addition of two of the most respected names in the Porsche aftermarket — Milltek Sport and Maxton Design — to the PSR 9Line catalogue.
Milltek Sport — Engineered in the UK, Built for Porsche
Milltek Sport needs little introduction. For over four decades, they've been manufacturing exhaust systems from aircraft-grade type-304 stainless steel at their facility in Derbyshire — and their Porsche range is among the most comprehensive in the business.
Our Milltek Sport collection launches with 11 products spanning some of the most sought-after Porsche platforms:
- 911 997.1 Carrera & Carrera S Rear Silencer(s) — Cup Version
- 911 997.2 3.6 & 3.8 Rear Silencer Delete
- 911 996 Turbo Free-Flow Manifolds
- 911 991.1 GT3 & GT3 RS Exhaust System
- 911 991.2 GT3 & GT3 RS Replacement Tips
- Cayman S 987 Gen1 & Gen2 / Boxster S 987 Gen1 & Gen2 Cat-Back Exhausts
- Cayenne 958 Turbo Cat-Back Exhaust, Secondary Catalyst Bypass & Replacement Tips
Whether you're chasing a cleaner exhaust note, freeing up power, or simply replacing worn components with something better than OE, Milltek's engineering does the talking.
Maxton Design — Precision Styling Without Compromise
Where Milltek Sport handles what you hear, Maxton Design handles what you see. Their precision-engineered body styling components are designed to sharpen the visual presence of your Porsche without altering its fundamental proportions — no wide-body kits, no compromised lines. Just considered, purposeful aerodynamic styling.
Our Maxton Design collection launches with 20 products across six Porsche model lines:
- 911 Carrera 4S 992 / Turbo S 992 — Side Skirts, Rear Splitters
- 911 997 Facelift / Carrera GTS — Central Rear Splitter
- Cayman S 987C / 718 GTS 982c — Front Splitters
- Cayenne Mk2 / Mk3 Coupe & SUV — Front Splitters, Side Skirts
- Macan Mk1 — Rear Side Splitters, Central Rear Splitter
- Panamera Turbo 970 / Sport Design / Turbo S E-Hybrid 971 — Front Splitters, Rear Splitters
- Taycan 4S / GTS Mk1 — Central Rear Splitter
Front splitters from £95, rear splitters from £100 — with fitment-specific options across the range.
Two Brands. One Standard.
Both Milltek Sport and Maxton Design share something with PSR 9Line — an uncompromising approach to what they put their name on. We're proud to stock them and look forward to growing both ranges as demand develops.
