BMW F80 Exhaust System Upgrades

BMW F80 Exhaust System Upgrades A performance exhaust is a modification that you get constant benefit from - at every change of the throttle you are rewarded with that tuned sound. It's not like other modifications where you may not realize all of its benefits all the time. It's an upgrade that you enjoy at all times when you're behind the wheel. We offer exhaust upgrades from multiple performance manufacturers like Borla, Corsa, Supersprint, and Akrapovic but we have also developed or sourced other exhaust systems to meet specific needs.

Active Autowerke Signature Performance Exhaust System - F80/2/3 M3/M4

The Active Autowerke F8X rear exhaust was carefully engineered to eliminate the unflattering sound of the factory M3 and M4 exhaust, while also allowing for optimum flow and resonance. Every effort was made in addressing the not so appeasing sound of the stock OEM exhaust, but in designing an exhaust worthy for an "M" car. We believe our rear exhaust combined with our mid-pipe offers the deepest sound and best performance of any other system on the market today.  Available for both models, this axle-back exhaust gives your BMW the deep, throaty, growl a car of its caliber should have had from the factory!

The most noticeable difference between the Active Autowerke F8X Rear Exhaust Section and the BMW factory exhaust is how they utilized the muffler. The design incorporates two mufflers that create a huge resonance chamber to further cancel out the “weed eater” noise.

This design also allows exhaust gases to crossover freely without being forced in a certain direction - eliminating back pressure without sacrificing that deep, aggressive rumble that some turbocharged cars are known for.

Note: Active Autowerke GUARANTEES that each and every F8X Rear Exhaust Section will be a precise fit. Every Active Autowerke F8X Rear Exhaust Section is test-fitted on our in-house F8X Exhaust Fixture as part of our quality control measures.

  • Made in the USA
  • 18+ WHP gain over stock*

F8X M3/M4 Magnaflow Performance Exhaust

Magnaflow's cat-back performance muffler features mandrel-bent stainless steel piping, new exhaust valves to work with the factory actuators, 3.5" tips, and an intoxicating sound. But perhaps the best attribute for this system is the price - less than any other major brand cat-back exhaust for this car. The Magnaflow name has been in the American performance car market for decades and now they're turning their experience to the German car scene. The Magnaflow has all of the features of other more expensive exhausts but at substantial savings and with a lifetime warranty. Magnaflow performance exhausts are Made in the USA.

The Magnaflow F8X M3/M4 system is offered in two sound levels -
Touring. Slightly louder and more aggressive sounding than stock. The Touring gives you most of the sound of the Sport but at a reduced volume to preserve the refinement of the stock exhaust.
Sport. Much more aggressive than stock with more roar and throaty sound. If you want to hear a lot more of the exhaust this is the version to go with. It's ever-present with plenty of burbles and pops to let you know its there. The sound is not "muscle car" like from other American exhausts but it's a more European sounding exhaust note. More drone will be present at highway speeds in higher gears.

Two finish options are offered: titanium-look and stealthy satin black.

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

F8X M3/M4 Turner Test Pipes
  • Perfect mix of more sound while eliminating rasp and rattle
  • Complements the stock sound - a refinement not a total transformation
  • Power & Torque gains
  • Preserve the stock muffler flaps and appearance

 

Our Turner M3/M4 Test Pipes delete the secondary cats for more sound and performance. One of the more common complaints about the M3/M4 exhaust is the lack of sound and it's clear why - two turbos, four catalytic converters, a resonator, and a large muffler with electronic flaps all work to dampen exhaust volume. We tried a number of different exhaust layouts but this was our favorite for a moderate increase in volume, "rasp and rattle" eliminated, easy install, low cost, and a power gain as a bonus!

Our M3/M4 front connecting pipes replace the stock section after the downpipes and before the resonator. They bolt to the downpipes with factory gaskets and hardware (will not fit with factory M Performance exhaust). We left the stock resonator in place because we felt removing it was too loud and it did a good job of tuning the exhaust note at certain RPM. With the Turner Test Pipes we got just enough exhaust sound in the cabin without it being obnoxious or intrusive. We especially love the subtle bark this setup gives when letting off the throttle!

Made in the USA!

Customer Feedback:

  • "RPower" - "After driving the car a couple of days during the work week I can give more of my thoughts on the Turner Test Pipes. The best word to describe the Turner Test Pipes is TRANSFORMATION! The start up noise is very loud and aggressive-no more boring weed eater lawnmower sound! These pipes make you want to rev the car out because the noise keeps getting better the higher you are in rev band. Great job Turner Motorsport for putting out a great product at a great price!"
  • "katzndogs" - "I too have the turner test pipes. I echo everything that RPOWER said. The sound is great and does truly want to make you rev out the car every time you give it gas. There is an awesome and loud bark/pop when you let off the gas in between shifts (6MT) or after spooling the turbos and then letting off. Down shifts sound more exciting and are noticeable louder. All in all you cannot go wrong with this system. GREAT job Turner!!"
