Key Information

Ixil Underseat Stainless Steel Exhaust System for KTM 300 EXC 

The Ixil Underseat Exhaust System is designed to give the KTM 300 EXC a distinctive racing appearance while improving exhaust flow and overall performance. Its compact underseat configuration enhances the aggressive off-road styling of the bike while delivering a sharper, more purposeful exhaust tone.

Constructed from durable stainless steel, the system provides excellent resistance to heat, corrosion and demanding off-road conditions. The kit includes both the silencer and a decat pipe, replacing the restrictive catalytic section of the OEM exhaust to allow freer exhaust flow and improved engine response.

A removable dB killer is fitted to the silencer to allow sound adjustment. The insert is riveted in place from the factory and can be removed if desired by drilling out the rivets. As this is a performance-focused system, it is not homologated for road use.

  • Look

    Your bike should look the way you feel as a rider. Whether you choose the right screen, levers, huggers or footpegs, the bike begins to reflect your own personality the way you like things to look, the pride you take in your machine, and the image you carry on the road. Cleaner lines, a shape that suits your taste, and a stance that matches the way you see yourself as a biker.

  • Sound

    The sound is the essence of your bike — and how it makes you feel when you ride it. The right silencer doesn’t just change the noise; it gives the bike a voice that matches its owners character. That deeper tone, the smoother pulse, the way it settles into a rhythm when you roll off… it all adds to the connection you feel with the machine.

  • Perform

    Performance is that feeling of being at one with your bike the moment you open the throttle. The last purchase made that connection sharper — cleaner pull, quicker reaction and a more willing surge as the revs build. It’s the confidence you feel when the bike flows with you through the S-bends, matching every input and settling exactly where you want it.
