Quicksilver, the manufacturer of high-end exhaust system upgrades for European Exotics introduces a true 'Cat-Back' performance exhaust system.  QuickSilver introduces the High Performance Lightweight Cat-Back Exhaust system. This system offers improved performance, a crisp sporting sound, with twin 3" Carbon Fiber tips and a straight-through design for optimum efficiency. 

This system does NOT remove the secondary catalytic converter in the 'B' pipe downstream from the flange.  Instead, it splices in downstream from the cat and before the pre-muffler and offers reduced backpressure for improved performance and great sounds!  If you prefer the system to connect at the flange and eliminate the secondary catalytic converter, see Quicksilver Performance Exhaust.

Fits the following models:

2007-2013 R56 MINI Cooper S Hatchback
2009-2015 R57 MINI Cooper S Convertible
2012-2015 R58 MINI Cooper S Coupe (non-JCW)
2012-2015 R59 MINI Cooper S Roadster (non-JCW)

See the Mini Cooper Quicksilver Cat-Back Exhaust customer review.

The Quicksilver solution!

Slightly quieter than the Sport System, this Cat-Back exhaust offers a nice sporting sound.  This system delivers on every aspect that our customers have requested:

• Great Sounds
• Performance Increase
• Light Weight
• Quality Construction
• Great looks
• Simple Installation

Performance Cat-Back Exhaust - connects downstream from the secondary cat and before the pre-muffler to preserve all emissions components. 

QuickSilver's Cat-Back exhaust system is designed to let the 4 cylinder turbo engine breathe more freely and sound great. Maintains the stock 2.25" diameter for maximum response. 

Drastic weight reduction - from 40 lbs. to 17.8 lbs!! Twin 3" Carbon Fiber exhaust tips gives your Mini an individual and assertive look.

Pleasant increase in volume with an encouraging 'Rasp' on acceleration - just right for Urban use.

The QuickSilver team has engineered the Cat-Back system's internal design to allow the volume and flow to increase in proportion with rpm. This provides the engine with a deeper tone at low engine speeds rising to a unique, higher pitched and crisper exhaust note at higher rpm.

Attention to detail has always been a hallmark of QuickSilver products and this is no exception. Using Type 304 austenitic stainless steel, the pipes are mandrel bent to keep a constant internal diameter throughout the length ensuring an even flow of exit gases.

Quicksilver supplies exhaust upgrades Worldwide for brands such as Aston Martin, Audi, Bentley, BMW, Bugatti, Ferrari, Jaguar, Lamborghini, Lotus, Maserati, Mercedes, and Porsche, just to name a few. QuickSilver Exhaust Systems have been a recognized maker of original and ‘Sports’ performance stainless steel exhaust systems for the World’s finest classic, prestige and exotic sports cars since 1973.

NOTES:

• The Cat-Back exhaust system is installed after the secondary catalytic converter to retain all emissions components.
• Will not cause 'Check Engine Lights'.
• 3 Piece design includes 'B' pipe, tail pipe, and exhaust tips.
• 25 Year Manufacturers' Warranty against corrosion.

CUSTOMER COMMENTS:

The sound is Awesome!!! Very deep and throaty at low RPM's and gets a bit higher pitched after 4500 RPMs. NO droaning at all at cruise speeds such as 45 or 65mph. It gets a bit bassy if you are at a high gear say 6th going 40mph and give it a little gas. Simple down shift takes care of it. I'll see after the breakin time how much it settles down. Right now though, it is great!!! You can really hear the turbo spooling up to redline now, pulls much faster and stronger, and revs faster as well. Traction control kept going off! There maybe something about that 30+hp they claim, I can really understand it being possible since it Does eliminate both the resonator and one Cat. Very happy!! and very simple install!!

For the simple pleasures of driving, nothing beats a great sounding exhaust to me like just cruising through a parking lot or hammering it on an on-ramp. Quicksilver exhaust to me, is the best sounding and performing exhaust. Install is a breeze, even if done in the home garage. One clamp to take off, then slip off the old exhaust, and install the new exhaust with a total of 3 clamps that includes the one for the tips!  Packaging, fit, and finish was perfect and I love the sound! NO drone at all at 60 or 70 mph, quiet during top gear motoring, then blip the throttle and downshift and a great roar comes from the back. Turbo spools much faster as well.




Sorry, this item will not ship to APO addresses due to oversized packaging.

NOTE: Some states (like California) have ever tightening requirements for emissions testing and inspections. Always check your local regulations on compliance for street use.
