Types of Exhaust Systems for the Triumph Speed 400

Slip-On Exhaust

A slip-on is the most popular upgrade for Triumph Speed 400 riders. It replaces only the muffler section of the stock exhaust, making it relatively easy to install. Slip-ons usually deliver noticeable improvements in sound while shedding a bit of weight. Performance gains are modest, but they offer great value.

Full System Exhaust

A full system replaces the entire stock exhaust, including the header pipes and muffler. This option delivers the most performance improvements and the most significant weight savings. However, it is more expensive and often requires remapping the engine to optimize fuel delivery and prevent lean conditions.

High-Mount vs Low-Mount Exhaust

  • High-mountPositioned closer to the tail section, offering a sporty look and increased ground clearance.
  • Low-mountRuns parallel to the frame, keeping a more traditional classic style while maintaining balance.

Materials Used in Aftermarket Exhausts

The material of the exhaust plays a big role in both aesthetics and performance. Riders can choose based on durability, style preferences, and budget.

Stainless Steel

Affordable, strong, and corrosion-resistant, stainless steel exhausts are a practical choice for daily riders. They are slightly heavier than other options but still lighter than stock systems.

Titanium

Known for its extreme strength-to-weight ratio, titanium offers excellent performance with minimal weight. It is more expensive but highly durable and ideal for riders seeking premium upgrades.

Carbon Fiber

Lightweight and stylish, carbon fiber mufflers give the Triumph Speed 400 a racing-inspired look. They require more care to prevent heat damage but are popular among riders who want aggressive styling.

Performance Benefits of Exhaust Upgrades

Installing an aftermarket exhaust for Triumph Speed 400 is not only about looks and sound it can also improve the way the bike performs. However, the actual benefits depend on the type of system chosen and whether additional tuning is applied.

Increased Power and Torque

A full system can improve airflow, helping the engine breathe better. This results in increased horsepower and torque, particularly noticeable at mid to high rev ranges. Slip-ons provide less dramatic gains but still enhance throttle response.

Better Throttle Response

Weight Reduction

Sound Options and Riding Experience

Deep and Throaty Tone

Sporty and Aggressive Sound

Full systems tend to produce a louder, sharper exhaust note that enhances the sporty feel of the bike.

Customizable Options

Some systems include removable baffles or dB killers, allowing riders to switch between louder and quieter setups depending on preference or local regulations.

Installation Considerations

Installing an aftermarket exhaust can range from simple bolt-on slip-ons to more involved full systems requiring professional assistance. Riders should consider the following before installation

  • Check whether engine remapping is required for optimal performance.
  • Ensure the exhaust is compatible with local noise and emissions laws.
  • Use high-quality gaskets and fittings to prevent leaks.
  • Consider professional installation for complex systems to avoid issues.
