F80 M3, F82 M4 Supersprint Section 1 Sport Cats

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.

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 part alters or deletes the emissions equipment on your car. Removing the secondary cats will not cause any check engine lights or faults but is against federal, state, and local laws for street-driven vehicles. This system was designed race and track use only. Because of this, we require a waiver of emissions compliance to be signed and sent in to TMS. You can download the waiver here.
