BMW F83 Performance Headers & Downpipes

BMW F83 Performance Headers & Downpipes 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.

F80 M3, F82 M4 Supersprint Racing Cat-less Downpipes

Free ground shipping!

For a true racing car, the biggest restriction in the exhaust system is the catalytic converters. On modern BMWs there are often two sets - a primary in the header/downpipe and a secondary further back in the exhaust. Removing these restrictions with a cat-less downpipe and straight pipes has enormous benefits for a track or race car: remove the restriction which unlocks huge power and torque gains, less heat (which can reduce power output), zero complication from a clogged or blocked catalytic converter, and less weight. These Supersprint M3/M4 cat-less downpipes are made from stainles steel and have no cats and mandrel-bent pipes for the best flow out the turbos. These will bolt on to the Supersprint or a stock section 1 front pipes. Special software or stand-alone engine management will be required to keep the check engine light and faults from appearing.

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!

Active Autowerke Performance High Flow Midpipe - F8X M3 M4

Active Autowerke has been an industry leader in engineering high quality BMW performance products for over 30 years. Dedicated to improving performance with the highest quality products, Active Autowerke is synonymous with making power. Their philosophy on developing refined BMW performance parts, with power in mind, and providing them to a large BMW community can be best characterized by our F80 M3 and F82 mid pipe – a valuable addition to our F8X BMW collection.

The Active Autowerke F8X Mid Pipe was specifically designed to eliminate the highly restrictive nature of the OEM F80 M3 and F82 M4 mid pipe – thus creating optimal exhaust flow and drastically improving performance. In addressing the annoying sound ( described by many like that of a weed-eater ) we needed to better understand the issue. After much research and testing we discovered the synchronization of the Turbos as the main factor in the sound. The solution was a single mid pipe which eliminated much of the annoying sound. The next challenge was making a large 3.5" pipe ( needed for optimum performance ) fit without ground clearance issues - thus the oval pipe. Engineered for an exact fit on both the F80 M3 and F82 M4, the difference in power with this mid pipe will be noticeable the moment it is installed!

Upon analyzing the F8X exhaust, Active Autowerke came to the decision that they can accomplish more with much less – therefore designing the F80 M3 and F82 M4 exhaust started with the highly restrictive mid pipe. With their design, they were able to drastically increasing exhaust flow, while virtually eliminating the "dueling 3-cylinders" sound.

Features:

  • 18+ WHP over stock*
  • 30+ LB-FT over stock*
  • Improved performance from less back pressure
  • Deeper & throatier exhaust note
  • Less restrictive, more free flowing
  • Lighter weight than factory system
  • Quicker turbo spool
  • Increased low end and mid-range power
  • Single-pipe design eliminates cheap “weed-eater” sound from factory exhaust
    * Performance gains when paired with Active Autowerke F8X Rear Exhaust Section

Active Autowerke Performance Stainless Catless Downpipes - F87 M3 M4

For over 30 years, Active Autowerke has been the one to turn to for high quality BMW performance products. Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about. The newest addition to our BMW F80 M3 and F82 M4 Collection, these F8X downpipes, is a true testament to our outlook on creating innovative products with performance in mind.

The F8X downpipes are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory F80 M3 and F82 M4 downpipes – therefore reducing radiant heat and increasing performance.

Active Autowerke Performance Coated Catless Downpipes - F87 M3 M4

For over 30 years, Active Autowerke has been the one to turn to for high quality BMW performance products. Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about. The newest addition to our BMW F80 M3 and F82 M4 Collection, these F8X downpipes, is a true testament to our outlook on creating innovative products with performance in mind.

The F8X downpipes are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory F80 M3 and F82 M4 downpipes – therefore reducing radiant heat and increasing performance.

The initial prototype design didn’t include the flex joints you see in the images above. Without these flex joints, the prototypes created an annoying vibration from within the cabin. They quickly realized the necessity of including flex joints into the design and went back to the drawing board. The works of art you see above are a culmination of years of experience engineering top-notch BMW exhaust products.

Made from 1.3-1.5mm thick 304 stainless steel, these F80 M3 and F82 M4 downpipes are finished with a White Lightning Exhaust Coating (performance enhancing, ceramic coating) from Swain Tech Coatings. Developed for precise fitment on both the F80 BMW M3 and F82 BMW M4, the difference in performance will be noticeable the moment you leave your driveway!

Unlike many of the cosmetic exhaust coatings, Swain Tech Coating’s White Lightning Exhaust Coating is a REAL ceramic coating – an exceptional insulating material. Since White Lightning is such a great insulating material, it is applied nearly five times thicker than a cosmetic coating. Additionally, White Lightning has performance enhancing benefits that cannot be matched by other cosmetic exhaust coatings.

Applied in a molten state, the ceramic coating bonds directly to the exhaust component. Typically a White Lightning coating can reduce radiant heat by roughly 35-55% - thus reducing engine bay and intake air temperatures.

“A 10°F reduction in intake air temperature provides a 1% increase in horsepower. A 30°F reduction equates to a 3% horsepower increase.” – Swain Tech Coatings

Furthermore, the insulating properties of the coating keep exhaust gases at the highest temperature possible creating greater exhaust gas velocity and higher efficiency. With the melting point of the White Lightning coating being over 3,000°F, you will not have to worry about damaging the coating.

The most remarkable feature of the White Lightning coating is how quickly it dissipates heat. Less than an hour after running hard, the downpipes will be cool to the touch allowing you to work around them without being concerned about scalding yourself.

Features:

  • 10-15 HP increase*
  • Flex joints to dampen vibration
  • Optional White Lightning Exhaust Coating by Swain Tech Coatings
  • 304-stainless
  • Quicker turbo response
  • Less restrictive, more free flowing
  • Improved low-end and mid-range performance
  • Made in USA
  • Lighter weight than factory downpipes
