Stainless Steel Muffler

Description

1. 1. 1. 1. Unleash the true potential of your Triumph 400. The factory exhaust system on the Speed 400 and Scrambler 400X is heavily restricted by strict emissions standards, choking engine performance and muting that iconic single-cylinder character. The MK Racing Full Exhaust System replaces the restrictive factory setup to deliver an aggressive sound profile, massive weight reduction, and superior exhaust flow.

   Built for riders who demand premium quality without compromising versatility, this high-grade stainless steel upgrade transforms how your bike looks, sounds, and accelerates.

   Why Upgrade to the MK Racing Full System?
   📉 Massive Weight Savings & Improved Handling
   The factory Triumph exhaust includes a bulky, heavy catalytic converter to meet Euro 5 / BS6 norms, weighing in at nearly 9.8 kg. By switching to the MK Racing Full System, you eliminate that dead weight entirely. Dropping this much unsprung mass instantly improves your bike’s power-to-weight ratio, making your Triumph 400 feel significantly lighter, more flickable in city traffic, and sharper in the corners.

   🔊 Deep, Aggressive Bass Note
   Say goodbye to the quiet, muted hum of the stock exhaust. The MK Racing muffler is acoustically tuned to produce a rich, deep, and throaty bass note that pops beautifully on deceleration. It gives the 398cc engine the aggressive growl it deserves without being obnoxiously loud at cruising speeds. (Note: Includes a removable DB killer so you can easily fine-tune the volume for daily commutes versus weekend blasts).

   ⚡ Seamless Modular Compatibility (Stock Muffler & Heat Shield)
   Designed with precision engineering, the MK Racing header pipe offers ultimate flexibility for your setup:

   Stock Slip-On Compatibility: Want the performance of a free-flowing header but prefer the look of the original exhaust? This header system is a direct bolt-on fit and fully compatible with the stock slip-on muffler on both the Speed 400 and Scrambler 400X.

   Factory Aesthetic: Keep your clean, modern-retro look intact. The header is meticulously designed to be 100% compatible with the stock heat plate/shield, ensuring OEM-level integration and heat protection.

   🚀 Performance & ECU Tuning
   Because this full system deletes the heavy catalytic converter, it vastly increases exhaust airflow. To maximize your horsepower gains and maintain an ideal Air-Fuel Ratio (AFR), we highly recommend pairing this exhaust with a piggyback fuel controller (like the FuelX Pro/Lite) or an ECU remap. Proper tuning ensures a buttery-smooth throttle response and a noticeable punch in the mid-range.
