Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

This axle-back exhaust system is manufactured entirely from titanium. This makes this system ideal for cutting weight while being structurally stronger than the OE exhaust system. The engineers at Akrapovic have retained the dual mode exhaust flap control from the original system. This allows the vehicle to have a more civilized, but deeper than stock sound at low speed. However, at higher RPM (or when selecting the S mode on the gearshift) the muffler is bypassed, creating a deep and sporty sound much more in keeping with the personality of the car. The included exhaust pipe tips are made completely from titanium OR a carbon fiber/titanium composite to add a high-end, refined style. Performance has not been left out of the design. The system dramatically reduces backpressure and is an excellent starting point for further engine tuning or turbo modifications. Even when installed on an otherwise stock vehicle a gain of 7.3 horsepower and 17.4 Nm/12.8 lbs-ft of torque are achieved. Furthermore, a weight reduction of 3.0 kg/6.6 lbs. is realized. The OEM catalysts are retained, so no reflashing of the ECU is required and the check engine light will not be triggered. Titanium muffler with integrated exhaust valves Statistics: +7.3 HP (at 4400 rpm) +17.4 Nm/12.8 lbs-ft of torque (at 2350 rpm) 3 kg/6.6 lbs. lighter than stock Not for sale outside the US or Canada.

These Supersprint sport catalytic converters are designed to be used with their Race cat-less downpipes. These are metallic sport HJS catalytic converters that are some of the best sport cats on the market. Using these with the M3/M4 cat-less downpipes will produce more power over the stock system with less heat and less complication but will require special software, modules, or a stand-alone engine management to keep the check engine light and fault codes from appearing. Straight pipes with no cats are also available for full-race systems where no cats are required. These front cats are designed to be used only with the Supersprint section 2 H-pipe. Supersprint/HJS sport cats, combined with cat-less downpipes, are the best way for producing power and still cleansing the exhaust gas.
