Unleash the full character of your supercharged MINI. Designed in-house specifically for the R52 and R53 Cooper S/JCW, our ECS cat-back exhaust combines precision engineering, premium materials, and a refined-yet-aggressive sound profile that adapts to your driving style.

Lightweight and well-balanced, the system delivers a deep, low-frequency tone during daily driving, while rewarding spirited throttle with sharp pops and burbles.

Design:

• Developed In-House using FARO ARM laser scanning and SolidWorks 3D CAD ensure a precision fit and consistent quality.
• 2.5" T304 CNC mandrel-bent Stainless Steel Tubing, brushed finish, 1.25mm wall thickness for strength, flow, and corrosion resistance.
• Straight-Through Turbo-Style Muffler – Perforated core with stainless packing for aggressive sound under load, yet smooth and refined at cruise.
• Adjustable Dual 3.5" Tips – 10mm of vertical adjustment allows perfect alignment with the rear valance.
• TIG-Welded & Back-Purged – Each unit is carefully hand-assembled for long-term durability and a clean, art-like finish.

Fitment & Installation

• Fabricated sheet metal brackets with OE fitment and reliability.
• Strategically placed slip joints for maximum adjustability and perfect fitment.
• T304 Stainless Barbed Hangers
• Resonated & Non-Resonated Options (both included) – Can change between a balanced tone or maximum raw character.
• Compatible Across Model Years – Includes brackets for both early (’02–’04) and late (’05–’06) production cars.
