The Stage 1.5+ Performance Upgrade kit with the Quicksilver Exhaust and JB+ Tune module blends the racing performance experience of Mini Mania with the demands of the enthusiastic MINI street driver.Available with Borla or Quicksilver Exhausts (Stage 1.5) and optional JB+ Tune (Stage 1.5+).

Fits the following models:

04/2012-2013 R56 MINI Cooper S Hatchback

Compatible with US and Canadian MINI Cooper S models.

Not compatible with JCW models.

This kit is all about improving the flow into and out of the engine - a basic but effective concept. Increased flow into the engine creates stronger combustion and a less restrictive exhaust results in a more efficient engine.

The Hi-Flow Performance exhaust system provides a gain in horsepower combined with the right amount of aggressive tones consistent with the performance image of the MINI Cooper S. The Hi-Flow Induction system with their free flowing re-usable air filter allows the engine to develop more horsepower while providing superior protection against dirt and debris, extending the engine life. The Hi-Flow Charge Pipe increases flow by eliminating the OEM sound chamber and increasing pipe diameter over stock. The Turbo Outlet Pipe increases flow by eliminating the intake muffler.

The JB+ Tune module features quick plug and play installation on the N18 and adds up to 20whp and 30wtq to your N18 equipped MINI. Fuel economy is unchanged during normal driving and the tuning works in conjunction with the DME rather than against it ensuring optimal but more aggressive boost levels with air/fuel ratios and timing to match. Boost is increased 2-4psi on average depending on the climate and conditions.

You will not believe the difference this kit will make! This kit can easily be installed by any serious DIY'er or by a local service shop in just a few hours.

Racing expertise for more fun in everyday driving. The Mini Mania Stage 1.5 Kit for the MINI Cooper S includes components whose development is derived directly from expertise gained from motor racing. This version of the new Mini Mania kits thus carries on a tradition which dates back 32 years of racing success of the Classic and BMW MINI. The resulting package fires the MINI Cooper S to new performance peaks and even greater driving fun!

Quicksilver Exhaust Upgrade

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.

This system delivers on every aspect that our customers have requested:

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

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.

NOTES:

[ ] This exhaust system is designed to bolt-in at the downpipe flange which removes the secondary catalytic converter. If you wish to keep the secondary cat, you can have a muffler shop cut and clamp or weld downstream to maintain the cat.

[ ] Will not cause 'Check Engine Lights'.
[ ] 3 Piece design includes 'B' pipe, tail pipe, and exhaust tips.
[ ] 25 Year Manufacturers' Warranty against corrosion.
[ ] Imported item - delivery can take 2+ weeks depending on inventory levels.

Hi-Flow Induction Kit

The 'Open-Air-Box' system gives you the abundance and unrestricted 360° of air source compared to OEM's sealed air box with flat filter and tube fed air source. During R&D, we installed temperature probes around the engine compartment and the gauge showed the inside temperature matched the ambient after vehicle speed past 20 mph. And by logging the Mass Air Flow (MAF) sensor also showed that open-air-box intake generated higher volume (gr/sec) of air going through the sensor. So when we had to choose between (a) cooler air at all speed with limited air source, vs. (b) cooler air at 20~ mph. with unlimited air source, the choice was pretty obvious.

MINI did a great job on 2011 model MCS in improving the turbo intake tube by replacing the soft rubber tubing with a full size and rigid ABS plastic one, similar to NM's aluminum/silicone version that we offer for the 2007~2010 MCS & JCW vehicles. So we decided to leave the inlet tube out and price out the kit to be more economical.

This Induction Kit is CARB APPROVED. EO# D-236-14

Hi-Flow Charge Pipe

The Hi-Flow Charge Pipe Upgrade replaces the factory necked-down hose between the intercooler and throttle body (cold-side) just before the intake manifold. The Hi-Flow Charge Pipe Upgrade includes a new CNC mandrel bent pipe and silicone couplers that will not expand under boost. The system eliminates OEM sound chamber which, in result, helps to increase turbo response as well as mid-range and top-end power.

Note: You will notice that a 'spigot' has been eliminated. This spigot was a connection to a sound chamber/generator which was used to quiet the intake 'sounds'. This was eliminated to improve performance.

Hi-Flow Turbo Outlet Pipe

The R55/56 MINI Cooper S engine utilizes turbocharger to pressurize the intake tract to force feed the engine air to produce power. The factory set-up uses an 'intake muffler' with reduced diameter and baffling that prevents 'smooth' airflow.

The Premium Hi-Flow Turbo Outlet Pipe 3-piece kit eliminates the intake muffler and replaces the factory rubber hose between the turbocharger and intercooler (hot-side) with a new CNC mandrel bent pipe and silicone couplers (upper and lower) that will not expand under boost.

Note: The height of this induction kit is the same height as the stock Cooper S Airbox. If your strut bar clears the stock airbox, it will clear this Induction system!

JB+ Tune Module

Featuring quick plug and play installation the N18 JB+ adds up to 20whp and 30wtq to your N18 equipped MINI. Fuel economy is unchanged during normal driving and the tuning works in conjunction with the DME rather than against it ensuring optimal but more aggressive boost levels with air/fuel ratios and timing to match. Boost is increased 2-4psi on average depending on the climate and conditions. Unlike other N18 piggyback tuners this one actually works and completely transforms the driving experience. This is how the car should have come tuned from the factory. Will be fully upgradable to higher stages when released. Literally installs and removes in less than 20 seconds.

Hi-Flow Intake Charge Pipe Upgrade

The MINI Cooper S engine utilizes a turbocharger to pressurize the intake tract to force feed the engine air to produce power. As such, a weak point has been identified that impairs the efficiency of this system.

The Hi-Flow Charge Pipe Upgrade replaces the factory necked-down hose between the intercooler and throttle body (cold-side) with a new larger diameter CNC mandrel bent pipe and silicone couplers that will not expand under boost. The system eliminates OEM sound chamber which, in result, helps to increase turbo response as well as mid-range and top-end power.

Turbo Outlet Pipe

The R56 MINI Cooper S engine utilizes a turbocharger to pressurize the intake tract to force feed the engine air to produce power. The factory set-up uses an 'intake muffler' with reduced diameter and baffling that prevents 'smooth' airflow.

The Premium Hi-Flow Turbo Outlet Pipe eliminates the intake muffler and replaces the factory rubber hose between the turbocharger and intercooler (hot-side) with a new CNC mandrel bent pipe and silicone couplers that will not expand under boost.

Items in this kit were carefully selected for optimum 'complimentary' performance.
