Akrapovic solved it with hydroforming — the header tubes are tapered from oval to cylindrical form on a hydroforming machine rather than welded from sections.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHeader tubes hydroformed from oval to round to meet the engine's oval inlets, with bushes and flanges designed for the same purpose\u003c\/li\u003e\n\u003cli\u003e3.3 kg lighter than the standard system — a 41 per cent saving\u003c\/li\u003e\n\u003cli\u003eBlack-coated high-grade titanium muffler outer sleeve, other parts in stainless steel\u003c\/li\u003e\n\u003cli\u003eSpecially tuned resonator in the link pipe, which is where the deep and full note comes from\u003c\/li\u003e\n\u003cli\u003eGains of 3.5 hp (2.6 kW) and 2.5 Nm, both at 10,000 rpm, measured against a standard Trident 660\u003c\/li\u003e\n\u003cli\u003ePlug-and-play with no remapping needed, unusual for a full racing system\u003c\/li\u003e\n\u003cli\u003eOne part covers the Trident 660, the Daytona 660 and the Tiger Sport 660\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHydroforming, and Why It Is Here\u003c\/h2\u003e\n\u003cp\u003eForming a tube from an oval cross-section into a round one without wrinkling it is the kind of problem that is normally solved by welding two pieces together and accepting a step in the gas flow. Hydroforming does it in one piece, using internal fluid pressure to push the metal into the die. The result is a continuous transition and no weld seam at the point where the gas is moving fastest.\u003c\/p\u003e\n\u003cp\u003eThe resonator in the link pipe is the other piece of engineering worth naming. It is tuned rather than generic, and on a three-cylinder engine that is what separates a full, deep note from a flat one.\u003c\/p\u003e\n\u003ch2\u003eTwo Restrictions\u003c\/h2\u003e\n\u003cp\u003eThis system does not fit together with the Triumph paddock stand bobbins — an original Triumph accessory. It does fit with the Triumph belly pan. And on Euro 5+ machines with two lambda sensors the engine check light will come on once the ECU detects a deviation in the stock catalytic converter's parameters; that is expected with this system, not a fault.\u003c\/p\u003e\n\u003ch2\u003eA Note on the Figures\u003c\/h2\u003e\n\u003cp\u003eAkrapovic publishes no structured dyno record for this part.
