{"product_id":"builder-series-tt","title":"Builder Series TT Slip-On Exhaust – Triumph Motorcycles (2016+)","description":"\u003cp\u003eSince 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.\u003c\/p\u003e\n\u003cp\u003eThe bikes that won there were not the quietest ones.\u003c\/p\u003e\n\u003cp\u003eWe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features \u0026amp; Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimpled Baffle\u003c\/strong\u003e — Shapes a deep, performance exhaust note that brings out the natural voice of your engine.
