The tone at idle is nice and deep, similar to a Borla system. The QuickSilver system has slightly more volume throughout the rpm range when compared to the Borla. Definitely not loud or annoying, but a nice sporting sound.

QuickSilver's newly developed 'Sports' exhaust system for the R56 Cooper S Hatchback is designed to let the 4 cylinder turbo engine breathe more freely and sound great. Customers have reported up to 35bhp performance increase!

Drastic weight reduction - from 40 lbs. to 18.6 lbs! Twin 3" upswept slash cut exhaust tips (DTM style) 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 'Sports' 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.

Here is a description of this product from a customer:

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!!
