NM Engineering Hi-Flow Induction Kit

The blue and black tube kits feature CNC mandrel bent aluminum pipe and finished with durable textured powder coat.   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.

This Induction Kit is CARB APPROVED! Product includes CARB exemption decal necessary to pass the visual inspection portion of the California Emissions test.

During R&D, we installed temperature probes around the engine compartment and the gauge showed the inside temperature matched the ambient after vehicle sped 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.

Quicksilver Cat-Back Exhaust Upgrade

Quicksilver's High Performance Lightweight Cat-Back Exhaust system for your MINI Cooper S offers improved performance, a crisp sporting sound, with twin 3" Carbon Fiber tips that fills out the rear bumper, and an all straight-through design for optimum efficiency.

This system does NOT remove the secondary catalytic converter in the 'B' pipe just downstream from the flange.  Instead, it splices in just downstream from the secondary cat and before the pre-muffler.   This system reduces backpressure for improved performance. 

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 Cat-Back exhaust system for the R56 Cooper S 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! 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 designed to install 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.
  • Imported item - delivery can take 2+ weeks depending on inventory levels.
