Build-Your-Own ECS Cat-Back Exhaust - F55/F56 Cooper S

Product Details

Bring out the sound and performance potential of your MINI Cooper S with the ECS Tuning Cat-Back Exhaust System. Engineered to reduce weight, improve exhaust flow, and deliver a more engaging driving experience, this system offers the perfect balance of sportiness and daily-driver usability.

From the factory, the B48 engine is quiet and restrained due to the turbocharger and stock downpipe acting as mufflers. ECS Tuning developed this system to retain the factory downpipe while replacing the remainder of the exhaust with a free-flowing, 2.5" T304 stainless steel setup, giving the car a more pronounced exhaust note, sharper response, and satisfying burbles without being overly aggressive.

This system is designed to fit both the F55 and F56 chassis and includes an extension pipe to accommodate the F55’s approximately 6-inch longer wheelbase, ensuring a precise fit on either model.

Key Features:

• Drops approximately 15 lbs compared to the factory system for improved performance
• Delivers a sporty, refined exhaust note with added character
• Constructed from mandrel-bent 2.5" T304 stainless steel for strength and longevity
• Designed to bolt directly to the factory pipe diameter with no welding required
• Swivel tip design for easy adjustment and optimal fitment
• Includes detailed step-by-step instructions for straightforward installation

Installation Notes
Installation requires a single cut to the factory exhaust. ECS Tuning provides clear cutting instructions to ensure a clean and accurate modification. Once cut, the new system slides directly onto the OEM connection point for a seamless, secure fit. No custom fabrication or welding is necessary; just measure, cut, and install.

For the best installation experience, Turner recommends having an Exhaust Pipe Cutter and Hanger Remover Pliers on hand (T#: 9609813).
