BMW F8X M3/M4 15-16 S55 "Cat-less" Downpipes

Our 2014-15 BMW F80 M3/ F82/3 M4 S55 Down Pipes are made from the same mandrel bent Polished, Fully TIG welded T-304 Stainless Steel with CNC Machined Flanges like all of our Exhaust products and feature our Limited Lifetime warranty. Our S55 Downpipes are 3" dia and then transition into 2.5" dia piping. We have also designed the flanges to float to allow for heat expansion (like the bellows in the OEM Downpipes). For Extreme conditions or just for peace of mind We now have a Stainless Steel Bellows Add-on option available when ordering our downpipes (+$150).  Made in the USA

 

The 2014-15 BMW F80 M3/ F82/3 M4 S55 Stainless Steel Down Pipes features:

* 12-16 WHP / 15-19 ft/lb torque Increase (Tune Numbers available soon)
* Optional Stainless Steel Bellows (Flex Section) Add on available (+$150)

* Made in the USA
 * Limited Lifetime Warranty

 

*Optional Black High Temp coating available (+ $200). The coating helps lower engine temp as it traps in Heat. The coating is capable of transferring heat faster than bare metal. Exhaust Gas will exit quicker through a High Temp Coated Exhaust Pipe.

 

 *A TTFS ECU tune is now available as an option when ordering the S55 Downpipes. When ordering The Tune and downpipes together you save $45 off the retail price of $1220 (removal of ecu in house) or $820 (if the customer removes and sends in ECU)

From Tuning Tech FS Website:

Our F8X M3/M4 tune enhances your stock and even modified S55 to the next level with factory style power delivery. We modify the factory engine parameters and flash your ECU based on your modifications and performance needs. Every tune is modified in-house. The price options include removal of the ECU to avoid dealer flash counter and dyno time at our top of the line all wheel drive enclosed dyno room with up to 90 mph airflow to provide the closest real life testing and output. We also offer M4 GTS flash for our clients looking for factory level boost without the price tag of a BMW M4 GTS. TTFS also provides dyno tuning for upgraded turbos and custom setup. Please contact us for your specific applications and possible remote tuning options.
