TEC Decat Front / Header Pipe – Speed 400 / Scrambler 400X

Important: If your bike is Euro 5+ (2025 onward), it will have an extra O2 sensor on the exhaust. If this is the case, this exhaust will NOT fit your bike. Please see the final image in the gallery – this is the sensor we mean.

Please watch our video below for full information on running this front-pipe, the benefits and for full sound tests.

NOTE – This listing is for the front pipe only, we sell this as part of our Full Exhaust System for these bikes, click here for the full kit.

Premium Materials: Crafted from full 304 stainless steel for durability.

Exclusive TEC Design: Unique and manufactured by TEC.

Fittings Included:

• 1x Stainless Steel Decat Front Pipe
• 1x Heat Shield Mounting Bracket
• 2x Heat Shield Mounting Bracket Clamps
• 1x Head to Front-pipe Gasket
• 1x Stop Rubber for side-stand
• Nut & washer for bottom sump guard bracket

No ECU Modification Required: However, we recommend removing the snorkel from the airbox to prevent the bike from running too rich at high RPM.

Compatibility: Can be used with the original Triumph silencer if you want to keep the E-markings on the original silencer.  Also can be used with the TEC silencer or any other aftermarket silencer (that fits the stock header pipe).

Weight Savings & Design Options:

• Maintains a clean, consistent angle in line with the bike and allows you to fit the stock Triumph end-can, our TEC silencer or any silencer that works with the Triumph header.
• Significantly lighter – as there is no cat, it is much lighter than the original.
• Can fit the original front heat shield or leave it bare, whichever you think looks best.
