why buy from us

Tegiwa BMW M135i M235i 335i 435i Stainless Steel Decat Downpipe Exhaust. This decat will fit all N55 engines from July 2013 onwards. The downpipe and flange are machined from the high grade T304 stainless steel and are TIG welded to ensure the best quality. The Tegiwa N55 decat will not only provide a sharper throttle response due to faster spool of the turbo but it will also provide noticeable power gains and a much more aggressive exhaust note too. The decat is mandrel bent to aid flow and ensure that no mid-range torque is lost.

This decat down pipe will fit the following models:

  • BMW 1 Series (F20) M 135 i, M 135 i XDrive 235 kW + 240 kW N55 engine
  • BMW 1 Series (F21) M 135 i, M 135 i XDrive, 235 kW N55 engine
