Since 1907, the Isle of Man TT has closed 37 miles of public roads on a small island in the Irish Sea once a year. Stone walls at arm's length. A mountain section that has ended careers. Riders who actually show up.

The bikes that won there were not the quietest ones.

We named this exhaust after the Isle of Man TT. Not as a tribute. As a standard. Every design choice was made to earn that name: the Two-Stage Core, the Dimpled Baffle, the raw stainless construction. Stock exhaust is built for compliance. The Builder Series TT is not.

The Two-Stage Core uses two baffles at two different diameters to control exhaust flow in sequence, preserving mid-range torque through corners, rolling throttle, and city traffic. The Dimpled Baffle shapes a deep, classic exhaust note that brings out the natural voice of your engine. At 2.4 pounds per silencer, it replaces stock mufflers at 8 to 10 pounds per side. The TT is a loud exhaust by design and is not compatible with dB Killers. For a quieter setup with mid-range tuning and dB Killer compatibility, see the Predator Pro 2.0.

Key Features & Benefits

Dimpled Baffle — Shapes a deep, performance exhaust note that brings out the natural voice of your engine. The TT is loud by design and is not compatible with dB Killers. For a quieter option with mid-range tuning, the Predator Pro 2.0 uses a Louvre Core and is dB Killer compatible.
Two-Stage Core — Two baffles at two different diameters control exhaust flow in sequence, maintaining mid-range torque through corners and rolling throttle. Exclusive to the Builder Series TT.
Significant Weight Savings — 2.4 pounds per silencer versus 8 to 10 pounds per side for stock. Physics, not marketing.
20-Gauge 304 Stainless Steel — Corrosion-resistant and rated for sustained heat cycling. Brushed finish requires no polishing and develops character over time.
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 on most fitments.

Frequently Asked Questions

Is the Builder Series TT a bolt-on install?

Yes. The Builder Series TT mounts directly to stock headers and factory mounting points. No cutting, welding, or permanent modification is required. Select your fitment above for model-specific installation details.

Do I need an ECU remap after installing this exhaust?

On most fitments, no ECU tuning is required when the factory catalytic converter is in place. The Thruxton 900 is the exception — it requires a tune update to the 2-2 Arrow Map at an authorized Triumph dealer. Select your fitment above for model-specific details.

How loud is this exhaust compared to stock?

The Builder Series TT is a loud exhaust by design. The Dimpled Baffle shapes a deep, performance exhaust note that is significantly more present than stock. It is not compatible with dB Killers. For a quieter option that is still mid-range tuned and dB Killer compatible, the Predator Pro 2.0 uses a Louvre Core.

Will I lose mid-range power with this exhaust?

No. The Two-Stage Core is specifically designed to maintain backpressure in the low-to-mid-range. Unlike perforated core designs that sacrifice torque for top-end noise, the TT keeps the engine responsive where riders actually use it.

What is the weight savings over stock?

The Builder Series TT weighs 2.4 pounds per silencer (4.8 pounds per pair). Stock mufflers typically weigh 8 to 10 pounds per side. That is approximately 11 to 15 pounds removed from the rear of the bike.

What is the difference between the Builder Series TT and the Predator Pro 2.0?

Different core designs, different sounds. The TT uses a Two-Stage Core with Dimpled Baffle — a performance exhaust note, loud by design, not compatible with dB Killers. The Predator Pro 2.0 uses a Louvre Core built from 18-gauge stainless steel, which produces a deeper, more classic sound. The heavier gauge allows all welds to be fully finished, giving the Predator Pro its cleaner appearance. The Predator Pro 2.0 is dB Killer compatible. Choose the TT for a performance note at full volume. Choose the Predator Pro 2.0 for a deeper, classic sound with the option to dial it back.

Is the brushed stainless finish the only option?

Yes. The Builder Series TT is available in brushed stainless steel. This finish is low maintenance, develops character over time, and pairs with any build direction.
