Clear BMW chassis

Please ensure your correct model is selected

When BMW began to offer more and more forced induction vehicles, some enthusiasts were upset and others were excited about the big power potential. While we love older, naturally aspirated BMWs, we LOVE forced induction BMWs. Upgrading your downpipe (or downpipes) is one of the easiest ways to reduce restriction and add more power to your BMW. We offer several brands, including our own designs, of downpipes for your BMW!

Free ground shipping! The factory 235/335/435 N55 exhaust system is pretty wide open with minimal restrictions - except for the catalytic converter. The factory cat is the biggest restriction so any exhaust work to gain more power is going to have to involve replacing it with something freer-flowing. Supersprint's downpipe incorporates a ultra high-flow HJS 100-cell metallic cat that flows considerably more than the stock ceramic part. It also uses bigger 80mm piping to minimize restrictions. 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! Supersprint metallic sport catalytic converters are sourced from HJS of Germany. For 30 years HJS has been supplying motorsports teams with sport cats when rules required them. HJS is now a worldwide leader in sport cat technology and performance. Rally cars, German DTM, and Formula 3 all rely on HJS for clean, reliable horsepower. Supersprint works closely with HJS to spec a catalytic converter that is correct for the vehicle and engine package. This allows for a substantial increase in flow but which, at the same time, keeps the environmental specs within European limits. With any high-flow catalytic converter, special software or other work may be required to keep emissions fault codes and check engine lights from displaying. Supersprint catalytic converters are sold for track and other off-road uses only. 100-cell cats have 100 honeycomb cells per square inch. While still cleansing the exhaust somewhat this is basically a straight-through exhaust. Dyno (M135i): +28hp / +17ft-lbs Supersprint downpipe with sport cat section 1, section 2 straight pipes performance muffler ​This product modifies (but does not remove or defeat) emissions equipment. For this reason this product may not be CARB compliant, and therefore not emissions legal in some states. Consult local laws and regulations in your area.
