Thirty seven miles. Stone walls, a mountain section, and no runoff. What came out of that race was a precise understanding of what performance actually requires: light weight, responsive power through every RPM range, and a sound that tells you the engine is working.\u003c\/p\u003e\n\u003cp\u003eThe Thruxton 1200 R, the Thruxton 1200 RS, and the Speed Twin 1200 are among the most capable machines in Triumph's modern classic lineup. The stock exhaust does not reflect that. Factory mufflers are heavy and quiet, and they hold back the 1200cc twin in exactly the RPM range where these bikes are most alive. The factory had its reasons. You have yours.\u003c\/p\u003e\n\u003cp\u003eThe Two Stage Core runs two baffles at two different diameters to control flow in sequence, holding backpressure through the low and mid range where these bikes live. The Dimpled Baffle brings out the natural voice of the engine. At 2.4 pounds per silencer against 8 to 10 pounds of stock muffler per side, all three bikes sharpen through corners immediately.\u003c\/p\u003e\n\u003cp\u003eThe TT is loud. That is the design, not a side effect, and it does not accept a dB Killer. If quiet matters more to you than volume, look at the Predator Pro instead, which takes an optional dB Killer.\u003c\/p\u003e","brand":"British Customs","offers":[{"title":"Default Title","offer_id":42113447526496,"sku":"BC902.2.110-BS-BR","price":599.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2384\/1971\/files\/builder-series-slip-on-exhaust-triumph-speed-twin-1200-2025-plus--13.jpg?v=1763037977","url":"https:\/\/britishcustoms.com\/products\/builder-series-tt-slip-on-exhaust-thruxton-1200","provider":"British Customs","version":"1.0","type":"link"}
