This design makes it ideal for riders who want performance gains, signature sound, and custom style with minimal fuss.

Why Upgrade to a Slip On Exhaust?

Upgrading to a motorcycle slip-on exhaust offers several practical and performance-oriented benefits:

1. Signature British Twin Sound

The Shorty Builder Series features a perforated stainless core that delivers a deep, throaty exhaust note. Compared to the stock muffler, it produces a richer, more immersive sound that brings out the character of Triumph’s modern classics.

• With the stock catalytic converter: full, deep tone without excessive volume
• Remove the cat: raw, aggressive sound for track or show use

A better-sounding exhaust makes every ride more engaging and fun.

2. Performance You Can Feel

Optimized exhaust flow translates into noticeable throttle responsiveness and improved low-end torque. Riders report:

• A livelier feel in city traffic
• Faster acceleration on backroads
• Improved connection between throttle input and engine output

While a slip-on won’t radically increase horsepower, these subtle gains make your Triumph more responsive and fun to ride.

3. Lightweight Construction

The Shorty Builder Series reduces weight compared to factory systems, thanks to its 20-gauge stainless steel construction. Benefits include:

• Better handling and maneuverability
• Improved balance and low-speed control
• Reduced unsprung weight for smoother ride feel

Even a modest weight reduction can noticeably improve overall riding dynamics.

4. Raw, Custom Aesthetic

With exposed welds, a brushed finish, and compact silhouette, this exhaust evokes the look of hand-built garage customs. It’s perfect for riders who want a bike that stands out visually while complementing the lines of Triumph’s modern classics.

5. No Tuning Required

The Shorty Builder Series is designed to work seamlessly with the stock ECU. Riders enjoy:

• Immediate sound and performance gains
• No remapping or aftermarket electronics required (unless you remove the catalytic converter)
• Plug-and-play installation that’s beginner-friendly

This eliminates one of the biggest barriers for riders upgrading their exhaust.

6. Durable Materials

Crafted from stainless steel, the exhaust resists corrosion and develops a unique patina over time, reflecting your journey and adding to the bike’s individuality. It’s built to last, even in harsh weather conditions or under spirited riding.

Installation Overview

One of the biggest advantages of the Shorty Builder Series is how easy it is to install:

• Estimated time: 30–60 minutes
• Skill level: Intermediate
• Tools: Basic hand tools included in the installation kit
• Includes: Pair of slip-on mufflers, stainless steel mounting hardware, custom spacers, and high-temp silicone

Installation involves removing the stock muffler, sliding on the new exhaust, securing the clamps, and checking alignment. No cutting or welding is required.
