"BMW E39 Touring 520i / 523i / 528i 9/'98 -> '00 Front exhaust with Metallic catalytic converter Right + Left

Product Details

When deciding on the right exhaust the hardest part is feeling confident in the best sound mixed with increased performance, this really leaves you to guess based on reputation. Fortunately, Supersprint has the reputation covered when it comes to BMW exhausts. For over 60 years their goal has always been designing and building the highest quality exhaust available. This has been achieved through extensive testing using real race teams to get the best feedback there is to offer, from the ones who demand the best everyday. Extensive dyno testing, high quality materials, and race team feedback are what allow Supersprint to extract the power from your engine, not just the noise.

This section includes a set of sport catalytic converters to work with the cat-less Supersprint performance headers. This section replaces the front exhaust ahead of the stock center resonator. The sport cats are designed to be a free-flow design for the least restriction but still providing a catalyzing effect to the exhaust. The less restriction is great for making more peak horsepower and torque. You can pair this section 1 with the Supersprint section 2 that deletes the center resonator and you will get more engine volume and a sporty BMW rasp from the M52/M54 inline-6. These cats have O2 bungs on the backside of the cats so you can extend your oxygen sensors to work with these cats. This will give you a near-stock system that's close to a Euro exhaust layout.
