Product Information

Ixil Underseat Stainless Steel Exhaust System for KTM 300 EXC 

Transform the look and performance of your KTM 300 EXC with the Ixil Underseat Exhaust System, designed to deliver a distinctive racing aesthetic and improved exhaust flow. The compact underseat layout enhances the bike’s aggressive off-road styling while producing a sharper, more purposeful exhaust tone.

Constructed from high-quality stainless steel, this system is built to withstand demanding off-road conditions, offering excellent resistance to heat and corrosion. By replacing the restrictive catalytic section with a decat pipe, it allows the engine to breathe more freely, improving throttle response and overall performance.
