Some upgrades for this CNY...
-Carbon Kevlar
GruppeM RAM AIR SYSTEMS epitomize the GruppeM philosophy of attention to detail. By replacing the factory air handling systems, increased airflow streams into the combustion chamber. Factory ductwork is replaced with heat-shielding carbon fiber or carbon kevlar with more or larger openings to capture the maximum amount of air. Lower intake air temperatures carry higher concentrations of oxygen, allowing for more energetic explosions and producing more horsepower and torque. Reliability is never sacrificed – high-efficiency, high-flow K&N air filters prevent contaminants from interfering with proper engine function.
Airflow velocity and temperature at the time of inhalation is critical to improved combustion. With the patented conical GruppeM filter shape, when air passes through the filter, it is compressed, and creates thrust similar to a jet engine, increasing the flow velocity. The limited space in the engine compartment is used as effectively as possible through extensive design. The shape of each GruppeM intake duct is designed to increase airflow velocity incrementally with the forced induction pressure.
These Borla mufflers will give your M3 a bit more growl and presence. These are stainless steel, high-flow mufflers that bolt on to the stock center section (or Borla midpipe). The stock M3 muffler is very large and softens the S54's exhaust note quite a bit. The Borla mufflers are much smaller and lighter with much-improved flow that increases horsepower and performance. Borla compared their mufflers with a common aftermarket brand and found their's flowed 10% better (

Every Borla is made with 304 stainless steel for the internals and muffler body. Unlike other systems that can use coated aluminum, mild steel, or 409 stainless, the Borla uses true 304 stainless on the inside as well as the outside. This prevents the muffler from rusting and deteriorating from the inside out.
