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).

Performance Catback Exhaust for pure unrestricted power and sound. This exhaust takes out all of the stop gates and pairs with the S58 for an iconic driving experience.

If you have driven an S58 car, even in stock form it feels like the sky is the limit.(If you haven't driven one, we are not sure why you are even looking into this exhaust)

When your driving an S58 equipped car such as the G80 M3 you can put your foot to the floor and it feels like the car would keep going and going, possibly with no limit. The G80 driving experience is great but there is always room for improvement. if dropping over 40lbs from just your exhaust and the gain in flow alone aren't enough to sell you, no problem. From enhancing the exhaust with smoother flow paths and taking out the bulky and restrictive muffler we saw gains up to 10hp and 14lb of torque on the stock ecu with zero tuning. Now that there are options for plug and play tunes as well as unlocking your ECU for custom tuning there is a much larger upside for power improvements. You will have to find the other restrictions holding you back from more power because it wont be the exhausts fault, this is as free flowing as it gets.

Here at Turner our mission was to amplify the G80/G82 with a proper catback exhaust system. To accomplish this goal, our engineers increased flow, reduced weight by 26lbs, and delivered an exhaust system that captures the full unrestricted sound of the sonorous twin turbo inline-6 S58 engine. The increase in flow was gained from dual 3.0" 304 stainless steel exhaust pipes that feed into straight-through free flowing rear section. We specifically designed this catback with flow in mind to ensure the exhaust would never be a restriction. Weight reduction is achieved by replacing the factory piping with lightweight 304ss for a more-than-modest weight advantage. The best part of the Race Inspired catback is the capability to perform far beyond the point that the factory exhaust. All of this plus the direct fitment and straight forward installation leads to our Turner Race Inspired Catback exhaust being the clear answer in your mission to find the best exhaust for your S58 powered G80 or G82.

Add a little more growl and sporty exuberance to the E32 740 with the Supersprint performance exhaust. This cat-back system has a tuned center resonator and sport muffler. Both are freer flowing than the stock 740 exhaust which gives a more sport-oriented sound and a modest power increase thanks to less restriction. Supersprint exhausts are often found on restored classic BMWs as a mild sport exhaust, thanks to their OEM quality and refined sound. The complete system is stainless steel and a direct fit to the stock catalytic converters (with the appropriate adapter pipe for the SWB or LWB).

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Fitment note: the resonator and muffler are the same for the 740i (SWB) and 740iL (LWB). But choose the correct adapter pipes below.

section:center resonator + rear muffler

connects to:stock cat section (see fitment note above)

tip style:90mm dual round

material:T304 stainless steel (both sections)

This item fits the following BMWs:
1993-1994 E32 BMW 740i 740iL
