BMW Exhaust Parts, Mufflers & Catalytic Converters for BMW 3 Series E92 (2007-2013)

Free ground shipping! 

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.

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.

The Supersprint Crossover Pipe will delete the rear resonator ahead of the rear mufflers. By removing the resonator, you can get more volume and growl from your exhaust as well as decrease exhaust restriction for slightly better power and torque. Deleting resonators makes a small but noticeable increase in overall volume so it's recommended that this is done after changing or removing mufflers. This x-pipe fits in section 2 of the exhaust - after the factory secondary cat section and before the rear mufflers. It's a direct install with Supersprint mufflers but any other set of mufflers may require custom professional installation to achieve a perfect fit.

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.

Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level.

Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

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.

Many people know that one of the main keys to getting power from a turbo is to open up the exhaust. Larger piping and less restrictions mean the exhaust gas can flow more easily which is less work for the turbo(s) and engine and that frees up torque and horsepower. These 100-cell metallic sport cats sit in oversized 60-65mm piping and are perfect for someone who installed cat-less downpipes but want some catalytic action on the exhaust to avoid bad smells and pollution. There are no crushed sections in the tubing, unlike the factory system, which contributes to improved flow. These are a direct replacement for the stock secondary cats and bolt to the turbo downpipe. At the back end these are clamped to a section 2 (stock or Supersprint X-Pipe).
