BMW M3 F80 / M4 F8x Alpha Competition Mid-pipe Exhaust Resonator / GPF Delete
 
This Alpha Competition kit, consisting of 3.5" / 89mm and 2x 2.75" / 70mm diameter stainless steel front and middle exhaust pipes, fits without modification from the downpipes to the rear silencer on the BMW M3 F80 and M4 F8x to eliminate the restrictive stock resonators and particulate filters on GPF equipped models. Providing an aggressive sound and a significant power gain due to the release of the exhaust, this Alpha Competition mid-pipe kit is a must-have upgrade for S55 engines.
