Introducing the VRSF 3.5" downpipe upgrade, which provides exceptional value for your N55 135i & 335i/xi. This mod offers significant improvements by removing the restrictive catalytic converter in the factory downpipe, leading to reduced back pressure, faster spool, increased power, and a more aggressive exhaust note. Moreover, our downpipe boasts a unique CFD optimized cast merge collector, which ensures a smooth transition from the turbo to mid-pipe.

At VRSF, we pride ourselves on crafting every downpipe by hand from tig-welded, mandrel-bent, 304-grade stainless steel. Our product comes with high-quality replacement hardware and mid-pipe gaskets, although we recommend purchasing the optional turbo clamp and gaskets if your car has more than 60k miles.

Cerakote High Temperature Ceramic Coating:

We are now including ceramic coating free of charge on our N55 downpipe. Our Cerakote's best thermal barrier coating helps keep the hot air inside the exhaust and out of the engine bay, lowering overall intake air temps and reducing engine coolant and transmission oil temps.


  • Made from hand crafted, tig welded 3.5″ 304 grade stainless steel.
  • Compatible with both right hand drive and left hand drive vehicles.
  • CFD optimized, cast stainless steel merge collector.
  • Smooth radius bends to decrease turbulence and increase flow.
  • CNC SS304 stainless steel flanges.
  • Gains from 25-30hp with tune.
  • Gaskets & mounting hardware included.
