Stainless front header for Triumph 400 – Compatible with stock muffler

More breathing, a bolder tone, and hassle-free installation

Designed specifically for the Triumph 400, this stainless steel front header replaces the original front section and connects directly to the factory muffler. It is aimed at riders who want to free up the single-cylinder’s breathing, gain everyday comfort, and enjoy a higher-quality exhaust line, all while keeping the look and balanced sound level of the OEM muffler.

Thanks to geometry engineered to smooth gas flow without compromising reliability, this front section sharpens throttle response and delivers a livelier engine feel. The use of quality stainless ensures excellent resistance to heat, debris, and oxidation while offering a clean, durable finish. Installation reuses the original mounting points for a neat, quick fit with no frame or subframe modification.

This product focuses exclusively on the stainless front section (header) and was developed to be compatible only with the rear section/stock muffler. It’s the ideal solution to enhance mechanical character and exhaust efficiency while keeping OEM discretion and compatibility.

Why upgrade the stock part?

OEM front exhaust sections are often designed to meet multiple cost, production, and standardization constraints. This can result in less efficient flow, heat-retention zones, and non-optimized weight. In use, you may see significant heat build-up, a finish that ages prematurely, or an engine that feels less responsive than desired.

• Bends and joints that can create turbulence

• Weight sometimes higher than actual needs

• Long-term susceptibility to oxidation

• Loss of punch at low and mid revs

By opting for this stainless front header specifically designed for the Triumph 400, you get cleaner flow, enhanced durability, and 100% OEM-compatible installation. The result is a more enjoyable bike without disrupting your original setup or visual line.

Ideal use:

• Daily riders seeking a more responsive engine while keeping the stock muffler

• Light custom enthusiasts looking for a simple, reversible, and reliable upgrade

• Urban and peri-urban use requiring smooth rev pick-up and direct feel

• Rides and road trips with a durable, resilient, and attractive exhaust line

• Riders wanting a clean intervention without structural modifications
