  • The S55 downpipes are machined from T-304 high-grade stainless steel and are tig welded in house
  • We have designed these downpipes with a flexi in to provide easier fitment and less stress on the exhaust.
  • Provides a sharper throttle response due to faster spool of the turbo alongside noticeable power gains and a much more aggressive exhaust note which sounds truly amazing
  • Produces lower temperatures and less exhaust backpressure due to the relief of the turbocharger. The cylinder charge is increased which contributes to maximum performance
  • There is also a substantial weight saving in comparison to the factory catalytic converter
  • Mandrel-bent for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque.
  • Finished in brushed stainless
These downpipes will fit the following models: 
  • BMW M3 F80 F82
  • BMW M4 F80 F82
  • BMW M2 Competition

Professional installation is recommended
