Headers are a bolt-on component that will make a huge improvement in how your BMW performs. As a replacement for your factory BMW exhaust manifold, our BMW headers provide a more direct path for exhaust gasses leaving your engine. Headers prevent your BMW's exhaust pulses from 'fighting' one another as they leave the head. The end result is that BMW headers give you more power and torque, and you'll love the high-winding top end push that a free-breathing engine exhibits. BMW headers are a must-have if you're doing any engine modifications on your vehicle. Along with a cold air intake, BMW headers provide the free-flowing exhaust necessary to get the most power out of your motor.
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. These Supersprint stainless headers are a true tubular, equal length design that bolt up for an immediate power gain. Power gains with a cat section depend on the type of cat. Supersprint sport cats for the E82 and E90/E92 are designed to work with their performance 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 and then to connecting pipes for whichever section 2 you are using. 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).

aFe POWER Twisted Steel Long Tube Headers are crafted from near-equal-length 1-1/2 inch, 16-gauge 304 stainless steel tubing with robust flanges for a reliable, leak-free seal. Unlike formed collectors that create turbulence and restrict flow, these headers use true merge collectors and optimized tube lengths, enhancing flow and performance through advanced pulse control technology. Fully TIG-welded, the smooth curves and increased diameter minimize restriction, allowing exhaust gases to flow efficiently for boosted performance and durability. Dual high-flow, 300 CPSI metallic catalytic converters maximize flow, delivering impressive low-end torque gains. The kit includes all components for an easy, modification-free installation.
