We understand the desire for a thrilling exhaust note without the annoyance of highway drone or interior vibrations. ECS's cat-back exhaust for your 335 incorporates this balance, offering a strategic blend of sportiness and practicality. Drawing from their extensive experience, particularly with N54 and N55 E chassis, ECS engineered an exhaust packed with innovative features, compatible with factory and aftermarket downpipes.

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).

When crafting the ECS exhaust systems, their primary focus is on achieving the perfect balance of sound and comfort. ECS's understand the desire for a thrilling exhaust note without the annoyance of highway drone or interior vibrations. The exhaust for your 135 incorporates this balance, offering a strageic blend of sportiness and practicality.

There is something about a cat-back exhaust that is just so good. Being able to unbolt and replace the entire visible exhaust gives you butterflies in your stomach. A fresh new exhaust and just knowing that things are about to get rowdy. This exhaust features twin 2.5" brushed pipes with flanges that bolt directly to your factory and aftermarket down-pipes. The dual 2.5" mid-pipes make their way toward the rear axle and converge into a single 3" exhaust section. The 3" exhaust section snakes through the rear section of the car making smooth dips and curves to make its way into a light-weight 3" turbo style muffler. Don't be fooled by the 135 muffler, the size is nothing but deceiving. The turbo-style muffler features an inner design that refines the exhaust note to perfection. An extraordinary mixture of both tone and volume. Paired with the 3" muffler is your choice of 3.5" exhaust tips that give your rear diffuser a sporty look that shouts performance.
Although both N54 and N55 share identical exhaust geometry, the N55 mid-pipes do not feature secondaries. Though the N55 cat-back is compatible with N54 downpipes this is not suggested. Supposedly this N55 catback sounds absolutely glorious on an N54, even with aftermarket downpipes.

The M2 M Performance exhaust is truly impressive! BMW has designed a performance exhaust system for the F87 M2 that makes the lithe M2 sound like a beast! The stainless M Performance exhaust replaces the stock system from the front pipe back and eliminates the center resonator. The sound transforms in Track Mode and is very aggressive and throaty. The rear muffler incorporates two bypass valves (one on each side) so you can choose between a street mode and open track mode. A Bluetooth remote is included to switch between modes (the standard Comfort-Sport-Sport+ settings will no longer control the exhaust valves). Professional installation is recommended as the exhaust flap controller must be connected to the stock wiring harness in the trunk.
