Builder Series TT Slip-On Exhaust – Triumph Motorcycles (2016+)

The Builder Series TT Slip-On Exhaust is a lightweight, performance-tuned exhaust designed for modern classic motorcycles. Riders want an exhaust that sounds deep, performs where it counts, and looks like it belongs on a custom build. The majority of aftermarket slip-ons use a single diameter perforated core designs that lose mid-range power and produce a thin, hollow tone. The Builder Series TT solves both problems with a Double-Step Core and Dimpled Baffle that deliver real sound and real performance in a single package.

Built from 20-gauge 304 stainless steel and weighing under 2.5 pounds per silencer, the TT replaces heavy stock mufflers with a raw, garage-built aesthetic. Stock exhaust is a great starting point. The Builder Series TT adds a purposeful look, a deep classic exhaust note, and responsive mid-range power that matches how riders actually use their bikes.

Key Features &Benefits

• Double-Step Core Design — Most exhaust cores are a straight tube full of holes. Exhaust flows straight through and takes backpressure with it. Lose backpressure and you lose mid-range pull. The Double-Step Core steps down in diameter halfway through, which slows the exhaust before it exits and keeps backpressure where the engine needs it.
• Dimpled Baffle Technology — A flat, thin baffle rings every time an exhaust pulse hits it — like striking a piece of sheet metal. That ring is the hollow, tinny note you hear from most aftermarket slip-ons. Dimpling the baffle stiffens it and stops the ringing. Take away the ring and all you hear is the engine: deep, full, and classic.
• 304 Stainless Steel Construction — Lightweight and corrosion-resistant. Under 2.5 pounds per silencer versus 8 to 10 pounds per side for stock.
• Exposed Weld, Garage-Built Aesthetic — Welds left visible and unfinished for a raw, vintage custom look that signals the bike was built by the rider.
• Bolt-On Installation — Mounts directly to stock headers and factory mounting points. No cutting, welding, or ECU tuning required.
