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 from Borla 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.

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!

Borla Exhaust

BORLA Performance Cat Back Exhaust 2 1/4" stainless steel system with twin chrome tips offers a nice deeper tone without being obnoxious - a nice 'performance' sound. It won't wake your neighbors at 5am!

For US Models only.

BORLA Cat-Back™ exhausts feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere.

Each system is built from premium Aircraft-Quality T-304 Stainless Steel, an alloy superior to T-400 series knockoffs, to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow and power, and precision computer-controlled CNC manufacturing ensures an accurate fit. Best of all, BORLA stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.

The Borla system installs 'downstream' from the secondary catalytic converter. This requires cutting of the stock system just behind the cat, where the Borla system is attached. The rest bolts right-in.

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

[ ] Great Sounds
[ ] Performance Increase
[ ] Light Weight
[ ] Quality Construction
[ ] Great looks
[ ] Simple Installation
[ ] Million Mile Factory Warranty!

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 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.

NOTE: Check with local emissions laws for compliance.
