      The DOMA 100119 expansion chamber is designed for KTM EGS 380, EXC 250, EXC 300, EXC 380, MXC 250, MXC 380, SX 250, SX 380 from 1998 to 2002. On a two-stroke, the expansion chamber isn't just a pipe: its cones send back a pressure wave that fills the cylinder better at the right rpm. Its shape gives the engine its character, and a dented pipe costs power.

      Key features

      • Handmade in Calais, France.
      • 1 mm raw steel, laser-cut parts, pressed and then welded on a jig.
      • Developed on the dyno and on the track.
      • Works with the stock silencer or a Doma silencer.

      Specifications

      • Brand: DOMA
      • Manufacturer part number: 100119
      • Engine: 2-stroke

      Who is it for?

      • Stock pipe dented or cracked after a crash.
      • Looking for more response and more power.

      Good to know

      Competition use only: this pipe is not road-legal.

      Fitting tips

      1. Reuse the stock connecting O-rings if they're in good condition (not included), or fit a new exhaust gasket.
      2. Offer up the pipe without forcing it, fit all the mounts, then tighten.
      3. Warm up the engine and check for leaks at the joints.
      4. Check the colour of the spark plug after the first few rides.

      Why DOMA?
