a standard upgrade for any F80 M3 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. \u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003eThe ARM F80 M3 Downpipes relieve the stressful

CNC machined v-band flanges offer a smooth transition of exhaust gasses from the the turbochargers to the ARM S55 Downpipes.  The body of the 3\" ARM F80 M3 Downpipes are constructed of SS304 Stainless-Steel and are threaded smoothly and perfectly though the space given by BMW towards the mid-pipe section.\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003eAny 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 F80 M3 Downpipes feature a smooth, gradual transition from the 3\" inlet to the 2.5\" exit for optimum exhaust flow.  \u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003eThe ARM F80 M3 Downpipes are a massive improvement over
