E9X M3 Supersprint Sport Catalytic Converters with Test Pipes are designed to replace the stock primary and secondary catalytic converters with high flow sport cats. With eliminating one set of cats and enlarging the piping the improved flow will increase performance and throttle response as well as increase sound and reduce weight. The straight-flow cat design allows much better flow than the stock cats, giving a significant horsepower and torque gain and a throaty sound. Removing the very restrictive primary cats results in a 25hp gain!

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.

requires:Supersprint section 2 x-pipe, p/n 980713

material:T304 stainless steel

Fitment Note: These sport cats were designed to be used only with the Supersprint section 2 x-pipe (p/n 980713) and Supersprint rear mufflers. Custom fabrication by an exhaust professional will be required to use these without the Supersprint exhaust sections. These cats include post-cat O2 sensor ports allowing for a complete installation by extending your original post-cat O2 sensors to the new location. Special Race software or module may still be required to keep the SES light and fault codes from appearing.

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.

The rear of the 335i and M3 have a very distinctive appearance thanks to their dual exhaust outlets. But the 328i models were equipped with the traditional and plain left rear outlet. With this Supersprint dual exhaust upgrade your 328i or 328xi can also benefit from this muscular and athletic exhaust look. The US E92 328i exhaust is unique to the US market and that has left a void for performance exhaust options. The European exhaust has different components and layout but the Supersprint Euro exhaust can be fitted to US cars. It consists of a stainless performance muffler and stainless center resonator that is clamped to the stock E92 secondary cat (or remove the cat with the Supersprint section 1 straight pipes). This makes for an excellent replacement exhaust system because the sound is sporty but refined and not too loud. It's a muted growl and throaty sound without being overly aggressive.

Fitment Notes: This system adds an additional pair of tips to the passenger side of the vehicle. Minor trimming of the rear bumper required to match the driver's side is required. Because this system uses parts that are not normally installed on the US exhaust some additional installation and fitment work is required. But the Euro and US cars share all of the same attachment points and hangers and this is the correct system for the Euro 330 coupe (called a 328 in the US market). Our kit includes the Euro installation hardware and gasket.

Supersprint sport cats for the E82 and E90/E92 are designed to work with their cat-less headers. The Supersprint sport cats are much freer-flowing than a traditional stock cat. With less restriction, less effort is required to move the exhaust gasses which will free up horsepower and torque. This cat section will mount to the Supersprint headers (p/n 789001) and then to connecting pipes for whichever section 2 you are using (p/n 789022). This section is built with O2 sensor bungs pre-installed after the cat if you wanted to extend your stock post-cat O2 sensors (however, special software may still be needed).

Supersprint's rear mufflers for the 335i and 335xi produce a pleasing but not intrusive exhaust sound. This set of mufflers are considered their 'street' system with only a modest increase in volume to give a hint of added performance without being obnoxious or annoying. This is a great set of mufflers for altering the exhaust note without drawing attention to yourself. You can also add additional Supersprint sections to better tune the exhaust to your preferances. This set uses the single 90mm round tip per side that fills in the bumper nicely. Another system is available that uses 4 80mm round tips.
