BR Motorsport are proud to introduce the BMW F80/F82 M3/M4 3″ decatted downpipes. These are made from 304 Stainless steel, with the original v-band fitment, beautifully CNC mandrel bent and welded to the highest of standard.
Unlike many other down pipes on the market, ours come with the flexible braided bands to compensate for engine movement and preventing excess stress being transferred through the exhaust system which in turn can cause potential cracking in the welds.
The downpipes will provide decreased spool times, increased noise, reduced weight & when fitted in-line with a full exhaust system and map, huge increases in horsepower & torque.
On request for further weight reduction and increased noise resonance these downpipes can be produced from aircraft grade Titanium at a slightly increased cost & delivery time.
Ceramic coating can too be provided, but is again at an increased cost & delivery time, just get in touch if you want further information.
• Adds 20-25HP to the wheels & 25-30TQ.
• Catia V5 designed cast flange for seamless flange to pipe transition.
• CNC mandral bent, TIG hand welded to the highest of standard, 304 stainless steel.
• Smooth radius bends to decrease turbulence & increase flow.
• LH / RH drive fitment.
Note: For race use only, map will be required to remove engine MIL light.
