PROFILE

The ARM F8X S55 Catted Downpipes are the ultimate solution for improving power, throttle response, and exhaust note on your S55 powered F8X.  Our goal for the ARM F8X Catted Downpipes was to provide a solution that would maximize power and torque, fit perfectly, and sound extraordinary.  The ARM S55 Catted downpipes incorporate two 200 cell catalysts to reduce emissions and exhaust odor while providing superior exhaust flow for your F8X!





Downpipes are considered a standard upgrade for any F8X owner looking to safely push their S55 engine beyond basic Stage 1 tuning.  With Stage 2 and up tuning, higher boost increases back-pressure at the OEM catalysts and chokes the S55's turbochargers, causing them to work harder and shortening their life. 
The ARM F8X Catted Downpipes relieve the stressful back-pressure caused by high-boost tunes, allowing the exhaust to flow freely, increasing power and torque, all while extending the longevity of your S55's turbochargers.  On our test car, after installing our F80 downpipes and switching to a Stage 2 flash we made 543whp and 547wtq, this is73whp and 126wtq gain over the stock results!
 
F80 M3 Downpipes Dyno Stage 2
Even with the ARM F8X Catted Downpipes installed on your stock-tune S55, you will notice an increase in power, torque and responsiveness.  Not to mention the incredible, head-turning sounds your M3 will make under part and full throttle. 

RUMBLE, NOT RASP.

The ARM S55 Catted Downpipes give your F8X an unparalleled sound that even other F8X owners will notice.  The deep, aggressive tone of the ARM F8X Catted Downpipes will stand out next to the all too familiar high-pitched rasp of other downpipes. 



CONSTRUCTION

Precision CNC machined v-band flanges offer a smooth transition of exhaust gasses from the the turbochargers to the ARM S55 Catted Downpipes.  The body of the 3" ARM F8X Catted Downpipes are constructed of SS304 Stainless-Steel and are threaded smoothly and perfectly though the space given by BMW towards the mid-pipe section.
Any downpipes that bolt up directly to the OEM mid-pipes must reduce to the 2.5"  to meet the size of the OEM mid-pipes.  Some aftermarket  downpipes use an abrupt, short reducer which causes turbulence in the exhaust gasses.  The ARM F8X Catted Downpipes feature a smooth, gradual transition from the 3" inlet to the 2.5" exit for optimum exhaust flow.  
The ARM F8X Catted Downpipes are a massive improvement over the OEM S55 downpipes, with precise fitment and brilliant finish the ARM S55 Catted Downpipes are the perfect solution for your S55 project. Our goal for the ARM F8X Catted Downpipes was to provide a solution that would maximize power/torque, fit perfectly, and sound uniquely extraordinary.  We are so confident that you'll agree we've achieved this, we back every set of our ARM F8X Catted Downpipes with a 30 Day Money-Back Guarantee and the ARM Lifetime Free-Replacement Warranty.
